5. Blurred Vision
High blood sugar can cause fluid shifts in the lenses of the eyes, leading to temporary vision changes. Persistent blurred vision should always be evaluated.
6. Slow-Healing Wounds
Cuts, bruises, or infections that take longer than usual to heal may indicate elevated blood sugar. Diabetes can impair circulation and weaken the immune system.
7. Frequent Infections
Recurring urinary tract infections, yeast infections, or skin infections may be linked to high glucose levels, which create an environment where bacteria and fungi thrive.
8. Tingling or Numbness in Hands and Feet
A burning, tingling, or numb sensation in the extremities may be a sign of nerve damage caused by prolonged high blood sugar levels. This condition is known as diabetic neuropathy.
9. Darkened Skin Patches
Velvety, dark patches of skin, particularly around the neck, armpits, or groin, can be a sign of insulin resistance. This condition is called acanthosis nigricans and is often associated with type 2 diabetes.
When to See a Doctor
If you notice several of these symptoms, do not ignore them. A simple blood test can determine your blood sugar levels. Early diagnosis and treatment can prevent serious complications.
Final Thoughts
These warning signs do not automatically mean you have diabetes, but they are important signals from your body. Listening carefully and seeking medical advice early can protect your long-term health.
If you are at higher risk — due to family history, being overweight, having high blood pressure, or leading a sedentary lifestyle — regular screening is especially important.
