If you live with diabetes, your feet are quietly doing a job most people never think about: telling you when something is wrong. The trouble is, diabetes can dull that early-warning system. Over time, high blood sugar damages the nerves and blood vessels in the lower legs, so a blister, a crack in the skin, or a small cut can go unnoticed until it becomes a serious wound. That's why podiatrists and diabetes organizations keep repeating the same message — check your feet every single day. It takes less than five minutes, and it may be the single most effective habit standing between you and a hospital stay or an amputation.

This article breaks down the three daily checks that matter most, why each one works, and how to build them into a routine you'll actually stick with.

Why Diabetic Feet Are So Vulnerable

Before getting into the checks themselves, it helps to understand what's actually happening inside a diabetic foot.

Nerve Damage Removes Your Warning System

Roughly 60–70% of people with diabetes develop some degree of peripheral neuropathy, nerve damage that most commonly shows up first in the feet, according to figures cited by Somers Orthopaedic Surgery & Sports Medicine Group. Neuropathy dulls the ability to feel pain, heat, and cold, which means an injury that would make anyone else wince can go completely unfelt in a diabetic foot. A pebble in a shoe, a too-hot bath, or a blister from a new pair of shoes can silently damage tissue for days before it's discovered.

Poor Circulation Slows Healing

Diabetes also narrows and hardens the blood vessels supplying the legs and feet, reducing blood flow and making it harder for the body to fight infection and repair damaged tissue, as explained in Somers Orthopaedic's diabetic foot care guidelines. Combine numbness with poor circulation and you get the exact conditions that allow a minor injury to progress into an ulcer, then an infection, and in the worst cases, gangrene.

The Stakes Are Genuinely High

This isn't an abstract risk. Research on lower extremity amputations shows that people with diabetes can be more than 20 times more likely to undergo a non-traumatic amputation than someone without diabetes, based on a national study out of the Republic of Ireland. And the consequences extend well beyond losing a limb: a five-year hospital analysis in Bucharest found that mortality within five years of a diabetes-related lower extremity amputation exceeds 70%, according to research published on NCBI. The good news, emphasized repeatedly by clinical guidance, is that most of these outcomes are preventable with consistent daily self-checks and prompt attention to problems, a point the CDC makes clear in its guidance for people managing diabetes.

With that context, here are the three checks worth building into your daily routine.

Check 1: The Visual Skin and Nail Inspection

This is the foundation of diabetic foot care, and nearly every major health authority lists it as step one.

What to Look For

Every day, ideally at the same time (many people do it right after a shower, before putting on socks), look over every part of both feet, including the soles, heels, and the skin between the toes. The CDC's tips for healthy feet recommend checking for cuts, redness, swelling, sores, blisters, corns, or calluses. You're also watching for cracked or unusually dry skin, ingrown toenails, discoloration, and any areas that look shiny or unusually pale, patterns highlighted by a Colorado State University Extension guide on diabetes and foot care.

How to See What You Can't Feel

Because reduced sensation means you can't rely on pain to alert you, vision has to do the work instead. If you can't comfortably bend down to see the bottom of your feet, the CDC recommends using a handheld or full-length mirror, or asking a family member to check for you. Clinical guidance published on the NCBI StatPearls diabetic foot care overview similarly instructs patients, including those who have already lost sensation, to use an unbreakable mirror or ask for help so that early problems don't go undetected.

Don't Skip the Toenails

Overgrown or improperly trimmed nails are a common, avoidable cause of injury. Trim nails straight across after bathing, when they're softened, and smooth any sharp edges with a nail file rather than cutting into the corners. If you notice a corn, callus, or ingrown nail, resist the urge to treat it yourself with blades, scissors, or medicated pads; the CDC and multiple podiatric associations advise leaving corn and callus removal to a foot doctor, since a small at-home mistake can turn into a serious wound.

What Counts as an Emergency Sign

Contact your doctor or podiatrist immediately if you notice any of the following:

A cut, sore, or blister that hasn't started healing within a day or two
Redness, warmth, or swelling around any area of the foot
Drainage, odor, or an open wound of any kind
A new area of numbness or tingling
Skin that has turned pale, blue, or black

Check 2: The Temperature Comparison Test

This check is less well known than the visual inspection, but the research behind it is striking.

The Science Behind It

Before a diabetic foot ulcer becomes visible, the skin at that spot often heats up first, due to inflammation and tissue breakdown happening beneath the surface. A landmark trial published in Diabetes Care, the American Diabetes Association's own journal, tested this idea directly: patients at high risk for ulceration used a handheld infrared thermometer to measure the sole of each foot morning and evening, comparing corresponding points on the left and right foot.

The results were compelling. Patients who caught temperature differences greater than 4°F between matching spots on each foot and reduced activity in response were significantly less likely to develop new ulcers. A separate PubMed-indexed randomized trial involving 173 people with a prior history of foot ulcers found that the "enhanced therapy" group using daily temperature monitoring developed far fewer new ulcers than groups relying on standard care or structured visual inspection alone. Another trial reported in the American Journal of Medicine found that patients who eventually ulcerated showed a temperature spike nearly five times larger at the ulcer site in the week before it appeared, compared with readings from patients who stayed ulcer-free.

How to Do It

Buy an inexpensive infrared skin thermometer (many cost under $50–$100).
Each day, measure the same handful of spots on both feet — commonly the ball of the foot, the heel, the arch, and the first, third, and fifth toe joints, as outlined in guidance summarized by Advances in Skin & Wound Care.
Compare each spot to the mirror-image spot on the opposite foot.
If any spot is more than 4°F warmer than its counterpart, treat it as a warning sign: reduce time spent standing or walking on that foot and call your provider.

A Reasonable Caveat

Not every study agrees on how reliably this method predicts an ulcer everywhere it's been tried; one trial conducted in Norway using a similar protocol found no statistically significant reduction in ulcer recurrence, a nuance discussed in a study protocol published on NCBI. Newer thermography research has also found that a chunk of "abnormal" temperature readings don't go on to become ulcers, as reported in a 2024 study in PubMed. The reasonable takeaway: temperature checks are a useful early-warning layer, not a replacement for the visual inspection, and any hot spot deserves attention rather than panic.

Check 3: The Sensation and Circulation Self-Check

The third daily habit addresses the two underlying problems described earlier — numbness and poor blood flow — directly.

Testing for Numbness

You don't need medical equipment to get a rough sense of whether sensation is changing. As you wash your feet, notice whether the water temperature feels the same on both feet, and pay attention to any areas that feel "asleep," tingly, or less responsive to touch than they used to- a self-check described by the Physical Therapy Board of California's diabetic foot brochure. A gradual increase in numbness, or numbness that's new or spreading, is worth reporting at your next appointment, and any sudden loss of feeling should be reported right away.

Checking Circulation

While drying your feet, look at color and warmth as circulation indicators. Feet that are unusually cold, pale, or bluish, especially compared with the rest of your leg, can point to reduced blood flow, a sign flagged in the Colorado State University Extension guide. You can also gently press a fingertip against the top of your foot or a toe; the color should return within a couple of seconds after you release. Slow color return can be another circulation clue worth mentioning to your provider.

Simple Habits That Support This Check

Wash feet daily in lukewarm (not hot) water, testing the temperature with your hand or elbow first rather than your feet, since reduced sensation can lead to accidental burns, per UF Health's diabetic foot care guidance.
Dry thoroughly, especially between the toes, where trapped moisture invites fungal infection.
Moisturize the tops and bottoms of your feet, but never between the toes.
Never walk barefoot, indoors or outdoors, since an unnoticed injury from stepping on something sharp is one of the most common ways an ulcer starts.
Always shake out and inspect the inside of your shoes before putting them on.

Building the Habit: A Simple Daily Routine

To make these three checks sustainable, most people find it easiest to pair them with something they already do every day, like showering or getting dressed:

After your shower, before socks: Visually inspect both feet top to bottom, including between the toes, using a mirror if needed.
While drying off: Do the quick sensation and circulation check — color, warmth, and any areas that feel different.
Once you're dressed: Take 60 seconds with the infrared thermometer to compare foot temperatures, particularly if you've been told you're at elevated risk for ulcers.

Keeping a simple log, even a few notes in your phone, can help you and your care team spot patterns over time. And remember that daily self-checks work alongside, not instead of, professional care. The CDC recommends a comprehensive foot exam by a healthcare provider at least once a year, and every three to six months for anyone having difficulty managing blood sugar or blood pressure.

Frequently Asked Questions

How often should I really check my feet? Every day, without exception, even if you feel fine. Because neuropathy can mask pain, "feeling fine" doesn't rule out a developing problem — daily visual checks are the standard recommendation from the CDC and diabetes care guidelines.

What if I can't see the bottom of my feet? Use a long-handled mirror, or ask a family member, caregiver, or home health aide to check for you. This is a standard workaround recommended by the CDC and echoed in clinical foot-care literature.

Do I really need an infrared thermometer, or is looking enough? Looking is the essential, non-negotiable habit. Temperature monitoring is an additional layer of protection that's been shown in multiple randomized trials to catch inflammation before it's visible, which is especially useful if you've had a previous ulcer or are considered high risk. If you're at lower risk, a visual and sensation check alone may be sufficient — ask your podiatrist what's right for you.

What should I do if I find a cut or blister? Clean it gently, cover it with a clean, dry dressing, and contact your doctor or podiatrist the same day, especially if you have neuropathy. Don't wait to "see if it heals on its own," since diabetic wounds can worsen quickly without you feeling it happen.

Can these checks actually prevent amputation? Consistent daily foot checks, combined with good blood sugar control, proper footwear, and regular professional exams, are widely credited by health authorities, including the CDC, with preventing most serious diabetic foot complications. Early detection is the whole point: nearly every severe outcome starts as a small, treatable problem that went unnoticed.

Is it normal for diabetic feet to feel cold or numb sometimes? Occasional cold feet can be normal, but persistent numbness, tingling, or coldness — particularly if it's new or getting worse — should be discussed with your healthcare provider, as it may signal nerve or circulation changes that need monitoring.

Why Diabetics Get Infections Easily And How To Prevent Them.

by Akore Odion September 05, 2026

Why diabetics get infections easily and practical ways to prevent infections through blood sugar control, hygiene, healthy eating, and proper skin care.

If you live with diabetes, you've probably noticed that a small cut takes longer to heal, a cold seems to hit harder, or urinary tract infections keep coming back. This isn't a

coincidence or bad luck — it's biology. Diabetes changes the way your body detects, fights, and recovers from infection, and understanding why is the first step toward protecting yourself. This guide breaks down the science behind diabetes-related infection risk and gives you practical, evidence-based steps to lower that risk.

How Diabetes Weakens the Body's Defenses Against Infection

At the center of the problem is one thing: elevated blood glucose. When blood sugar runs high over time, it interferes with several of the body's natural defense systems at once,

rather than just one.

High Blood Sugar Blunts Immune Cell Function

White blood cells — especially neutrophils and macrophages — are the immune system's first responders. According to MyHealth Alberta, high blood sugar impairs these cells' ability to travel to an infection site, remain there, and destroy invading microorganisms. Research summarized in a PMC review on type 2 diabetes and immune function explains that hyperglycemia causes a dysfunction in the immune response, making it harder for the body to control the spread of pathogens once they've taken hold.

Some of this dysfunction goes deeper than white blood cells alone. A ScienceDirect review of immune dysfunction in diabetes notes that people with poorly controlled type 2 diabetes have measurably lower counts of dendritic cells, the cells that link the body's rapid, non-specific immune response with its more targeted, adaptive response — leaving a gap in the body's overall coordination against infection.

Glucose Itself Feeds Bacteria and Weakens Tissue

It isn't just that the immune system slows down — the environment inside the body actively becomes more hospitable to pathogens. Research published in Infection and Immunity points out that glucose is a preferred fuel source for several bacterial pathogens, and hyperglycemia can directly accelerate bacterial growth and virulence. High glucose levels also promote biofilm formation and tissue adherence, which is one reason chronic wounds like diabetic foot ulcers are so difficult to clear.

Poor Circulation Slows Healing

Diabetes is closely linked to atherosclerosis, or plaque buildup in blood vessels. When circulation to an area is reduced, fewer immune cells, less oxygen, and fewer nutrients reach the place of an injury or infection. The Yale School of Medicine explains that this combination of high blood sugar and poor blood flow to the extremities is a major reason wound healing becomes so difficult in people with diabetes, particularly in the feet and lower legs.

Nerve Damage Hides the Warning Signs

Diabetic neuropathy, or nerve damage, sneakily compounds the problem: it can reduce your ability to feel pain, heat, or pressure. That means a blister, cut, or pressure sore on the foot can go unnoticed and untreated for days or weeks, giving an infection time to take hold before you even know something is wrong.

Which Infections Are Diabetics Most Prone To?

Diabetes doesn't raise the risk of every type of infection equally. A well-known PubMed cohort study that followed thousands of patients over 12 months found that people with type 1 and

type 2 diabetes had a significantly higher risk of lower respiratory tract infections, urinary tract infections, and both bacterial and fungal skin infections compared with people without diabetes — and that the risk climbed further with each recurrence.

Skin and Soft Tissue Infections

High glucose levels weaken the skin's natural barrier, giving bacteria an easier entry point through even minor cuts or abrasions, according to a clinical overview from Dr. Mohan's Diabetes. Foot infections deserve special attention here, since the combination of neuropathy and poor circulation makes the feet the single most common site of serious diabetes-related infection.

Urinary Tract Infections (UTIs)

A systematic review in PMC found that excess glucose spilling into the urine (glycosuria), combined with hyperglycemia-related immune impairment, significantly raises UTI risk in people with diabetes — and that diabetics are also more likely to develop UTIs caused by drug-resistant bacteria. According to GoodRx, keeping blood sugar within a normal range is one of the most effective ways to reduce this risk.

Fungal and Yeast Infections

Yeast thrives on sugar, so it's no surprise that people with diabetes are more prone to candidiasis. Medical News Today reports that extra glucose excreted in urine and sweat creates ideal conditions for Candida albicans to overgrow in warm, moist areas such as the mouth, skin folds, feet, and genitals — and once yeast colonizes an area, recurrent infections become more likely.

Respiratory Infections

Diabetes also raises the risk and severity of respiratory illness. An Endotext clinical review cites a large Danish study showing the relative risk of hospitalization for community-acquired pneumonia was notably higher in diabetics, and that this risk rose in step with poorer long-term blood sugar control (as measured by HbA1c). This is also why annual flu shots and pneumococcal vaccination are specifically recommended for people with diabetes.

Rare but Serious Infections

In cases of very poorly controlled diabetes, particularly diabetic ketoacidosis, the body becomes vulnerable to unusual and aggressive infections. MyHealth Alberta describes two examples: malignant external otitis, a severe Pseudomonas infection of the outer ear, and mucormycosis, a fast-moving fungal infection of the nose and sinuses. Both are medical emergencies, though they remain uncommon overall.

How to Prevent Infections When You Have Diabetes

The encouraging news is that most diabetes-related infections are preventable. The strategies below target the exact mechanisms described above.

Prioritize Blood Sugar Control

Every source in this article circles back to the same starting point: consistent glucose management. The CDC notes that keeping blood sugar within your target range is one of the most important things you can do to prevent nerve damage from progressing — which in turn protects you from the infections that stem from it. Work with your healthcare provider on a target A1C, monitor glucose as recommended, take medications consistently, and don't skip follow-up appointments.

Make Daily Foot Checks a Habit

Because neuropathy can mask injury, a visual check is essential. The American Diabetes Association recommends:

· Checking your feet every day for cuts, redness, swelling, blisters, or cracks — use a mirror to see the bottoms of your feet if needed.

· Washing feet daily in warm (not hot) water and drying thoroughly, especially between the toes.

· Never applying lotion between the toes, since trapped moisture there can lead to infection, per CDC guidance.

· Wearing well-fitting socks and shoes at all times — including indoors — to avoid unnoticed injuries.

· Trimming toenails straight across to prevent ingrown nails, and leaving corns, calluses, or ingrown nails to a podiatrist rather than treating them yourself.

· Scheduling a comprehensive foot exam at least once a year, or more often if blood sugar or blood pressure are difficult to manage, as advised by the CDC's clinical guidance for providers.

Practice Good Hygiene Everywhere, Not Just Your Feet

Basic hygiene habits carry more weight for people with diabetes because the margin for error is smaller. Wash your hands regularly, keep skin clean and moisturized (except between the toes), and treat even minor cuts or scrapes promptly with proper wound cleaning and monitoring rather than waiting to see if they heal on their own.

Stay Up to Date on Vaccinations

Because diabetes increases the severity of respiratory illness, staying current on influenza and pneumococcal vaccines is specifically recommended for this population, as noted by MyHealth Alberta. Speak with your provider about which vaccines are appropriate for your age and health history.

Watch for Signs of UTIs and Yeast Infections Early

Because these infections are so common in diabetics, don't dismiss symptoms like burning during urination, unusual discharge, persistent itching, or a strong urge to urinate frequently. Early treatment reduces the chance of the infection becoming recurrent or spreading to the kidneys, a serious complication highlighted in the PMC review on diabetic UTIs.

Don't Smoke and Stay Physically Active

Smoking further restricts blood flow to the extremities, compounding the circulation problems diabetes already causes, according to the CDC. Regular movement — even 10 to 20 minutes a day — helps improve circulation and supports better glucose control overall.

Build a Care Team

Diabetes-related infections, especially foot infections, are best managed with a team approach. The American Diabetes Association points to research showing that a multidisciplinary approach involving an endocrinologist, primary care doctor, podiatrist, and, when needed, vascular or infectious disease specialists led to more than a 30% reduction in major amputations in one study. Don't hesitate to ask your primary provider for referrals if you notice recurring infections.

The Bottom Line

Diabetes doesn't just raise blood sugar — it reshapes how your entire body senses, resists, and recovers from infection. High glucose dulls immune cell function, feeds bacteria and fungi directly, narrows blood vessels that would otherwise deliver healing resources, and can numb the very nerves that would normally warn you something is wrong. The result is a higher risk of skin infections, UTIs, yeast infections, and respiratory illness, along with a higher chance that any of these will become severe.

The good news is that the prevention strategies are straightforward, even if they require consistency: manage blood sugar, check your feet daily, keep up with hygiene and vaccinations, treat minor symptoms early, and lean on your healthcare team rather than waiting until a small problem becomes a big one.

Frequently Asked Questions

1. Does having diabetes mean I have a weak immune system? Not exactly. Living with diabetes doesn't automatically mean a weaker immune system. Still, according to Dexcom, unmanaged blood sugar can make it harder for the immune system to defend against illness and infection. Good glucose control significantly narrows this gap.

2. What is the most common infection in people with diabetes? Skin and soft tissue infections, urinary tract infections, and fungal infections are among the most frequently reported, according to a long-term cohort study on PubMed. Foot infections are considered the most serious because they carry the highest risk of hospitalization and amputation.

3. Can lowering my blood sugar reverse existing infection risk? Better glycemic control reduces ongoing risk and improves healing capacity, though it can't undo permanent nerve or vascular damage that has already occurred. Consistent blood sugar management still meaningfully lowers the frequency and severity of new infections.

Should people with diabetes get a flu shot every year? Yes. Because diabetes raises the risk of severe complications from respiratory infections, annual influenza vaccination and pneumococcal vaccination are specifically recommended for this group.

How often should a diabetic see a podiatrist? The CDC recommends a basic foot check at every healthcare visit, a comprehensive foot exam once a year, and more frequent checks — every three to six months — for anyone who has difficulty managing blood sugar or blood pressure.
