Unusual Fatigue and Irritability
One of the less obvious but equally important signs of diabetes is a general feeling of fatigue and irritability. When the body's cells are deprived of glucose, a vital source of energy, it can lead to a significant drop in stamina and mood. This type of exhaustion is not resolved by simply sleeping or resting. The American Diabetes Association describes how the lack of insulin to transport sugar into cells can make a person feel tired and irritable, impacting daily functioning.
Blurred Vision
Changes in vision can often be a red flag when it comes to identifying diabetes early. High blood sugar levels can cause the lens inside the eye to swell, altering your ability to see. This symptom should not be overlooked as it can evolve from mild blurring to significant vision issues if not addressed. According to Mayo Clinic, fluctuating fluid levels in the body can lead to the swelling of the eye lens, making it difficult for the eyes to focus, thus causing blurry vision.
Slow Healing of Cuts and Wounds
Another concerning sign of diabetes is the slow healing of cuts and wounds. High sugar levels in the blood can affect the body's ability to heal and fight infections. In severe cases, this can lead to complications such as infections or ulcers, particularly on the feet. Research from Healthline supports the finding that poor blood circulation and nerve damage, both common in diabetes, can significantly delay healing processes.
Frequent Infections
Individuals with diabetes are more susceptible to frequent infections, particularly yeast and bacterial infections. The excess sugar in the body provides an optimal breeding ground for bacteria and fungi, contributing to a higher risk of infections. This symptom can often be a telltale sign of diabetes, especially if infections recur more frequently than usual or are difficult to resolve.
