Common signs of diabetes include frequent urination, excessive thirst, constant hunger, and unexpected weight loss. Other symptoms include blurred vision, fatigue, slow-healing wounds, and numbness in hands or feet. Type 1 diabetes often appears suddenly, while Type 2 develops gradually.
These signs occur because of high blood sugar levels, which affect many organs. If left untreated, diabetes can lead to heart disease, kidney damage, and vision loss. Early diagnosis and lifestyle changes like healthy eating and exercise can prevent complications. Blood tests like fasting glucose or HbA1c confirm the diagnosis. Always consult a doctor for evaluation.
