These can be signs of diabetic ketoacidosis, a potentially life-threatening complication.

Do not wait for symptoms to improve on their own.

7. Persistent Itching or Dry Skin

Dry skin is common, especially during colder weather, after frequent bathing, or when indoor air is dry.

However, persistent itching may sometimes be associated with diabetes.

How can diabetes affect the skin?

High blood glucose can contribute to dehydration.

Frequent urination may cause the body to lose additional fluid, which can make the skin feel dry.

Diabetes can also affect circulation and nerve function over time.

Some people with diabetes experience itching associated with fungal infections, skin irritation, or other dermatological conditions.

However, itching alone is not a reliable indicator of diabetes.

Common alternative causes include:

• Eczema

• Allergies

• Dry weather

• Contact dermatitis

• Medication reactions

• Liver or kidney disorders

• Fungal infections

What should you do?

If your skin is dry, consider gentle skincare practices:

• Use a fragrance-free moisturizer.

• Avoid excessively hot showers.

• Choose mild cleansing products.

• Drink fluids according to your medical needs.

• Avoid scratching irritated skin.

If itching persists, becomes severe, or occurs alongside other possible diabetes symptoms, consult a healthcare professional.

People with diabetes should pay particular attention to skin infections and wounds, especially on the feet.

8. Tingling, Burning, or Numbness in the Hands and Feet

Tingling, burning, or numbness in the extremities can be associated with nerve damage.

One possible cause is diabetic peripheral neuropathy.

This condition usually develops after prolonged exposure to elevated blood glucose, although nerve problems can occasionally be present when type 2 diabetes is first diagnosed.

What does diabetic neuropathy feel like?

People may describe symptoms such as:

• Pins-and-needles sensations

• Burning pain

• Numbness

• Sensitivity to touch

• Electric-shock-like sensations

• Reduced ability to feel temperature

• Pain that becomes more noticeable at night

Symptoms often begin in the feet and may gradually extend upward.

Some people experience symptoms in their hands as well.

Why is nerve damage dangerous?

Nerve damage can reduce sensation.

A person may not notice a blister, cut, burn, or small injury.

If circulation is also impaired, wounds may heal more slowly and become infected.

This is one reason foot care is particularly important for people with diabetes.

Does tingling always mean diabetes?

No.

Tingling and numbness can also be caused by:

• Vitamin B12 deficiency

• Nerve compression

• Spinal problems

• Alcohol-related nerve damage

• Certain medications

• Thyroid disorders

• Other neurological conditions

If symptoms persist, worsen, or interfere with daily activities, seek medical evaluation.

Sudden numbness or weakness affecting one side of the body, especially with difficulty speaking or facial drooping, requires emergency assessment because it may indicate a stroke.

9. Slow-Healing Cuts and Frequent Infections

A small cut that seems to take unusually long to heal may deserve attention.

Diabetes can affect several processes involved in wound healing.

Why can high blood sugar interfere with healing?

Persistently elevated blood glucose can affect:

• Blood vessel function

• Immune system activity

• Nerve function

• Tissue repair

• Circulation

These changes can make it harder for the body to respond effectively to injury.

People with diabetes may also be more vulnerable to certain infections.

Common areas of concern include the feet, skin, gums, and urinary tract.

However, not every slow-healing wound is caused by diabetes.

Poor nutrition, smoking, vascular disease, infection, certain medications, and other health conditions can also interfere with healing.

What should you watch for?

Seek medical evaluation if you notice:

• Wounds that repeatedly fail to heal

• Increasing redness or swelling

• Pus or unusual drainage

• Persistent pain

• Fever

• Skin that becomes dark or discolored around a wound

People with diabetes should not ignore foot wounds.

A small injury can become serious if circulation or sensation is impaired.

If you have diabetes and develop a foot ulcer, spreading redness, or signs of infection, seek prompt medical care.

Do not rely on home remedies alone.

Understanding How Diabetes Affects the Body

To understand why these symptoms occur, it helps to know how glucose regulation normally works.

When you eat carbohydrates, your digestive system breaks them down into glucose.

Glucose enters the bloodstream and provides energy to cells.

The pancreas produces insulin, a hormone that helps regulate blood glucose.

Insulin allows glucose to move into many cells and helps the body store energy for later use.

In diabetes, this system becomes disrupted.

There are several major types of diabetes.

Type 1 Diabetes

Type 1 diabetes is an autoimmune condition in which the immune system attacks the insulin-producing cells of the pancreas.

As a result, the body produces little or no insulin.

People with type 1 diabetes require insulin treatment to survive.

The condition can develop at any age, although it is often diagnosed during childhood or adolescence.

Symptoms may appear relatively quickly.

In some cases, the first presentation is diabetic ketoacidosis.

Type 2 Diabetes

Type 2 diabetes is characterized by insulin resistance and a gradual decline in the body's ability to produce enough insulin.

The body may initially produce additional insulin to compensate.

Over time, however, this compensation may become insufficient.

Type 2 diabetes often develops gradually.

Some people have few noticeable symptoms for years.

Risk factors include:

• Family history

• Increasing age

• Physical inactivity

• Certain patterns of weight gain

• Previous gestational diabetes

• Some genetic and metabolic factors

Type 2 diabetes can also occur in people who are not overweight.

It is not simply a disease caused by eating too much sugar.

Prediabetes

Prediabetes means blood glucose levels are higher than normal but not high enough to meet the diagnostic criteria for diabetes.

It is associated with an increased risk of developing type 2 diabetes.

Many people with prediabetes have no symptoms.

That is why screening can be important for people with relevant risk factors.
