Diabetes and its Complications

Diabetes is a condition in which your body can not absorb blood glucose. For the absorption of glucose in your blood, your body secretes a hormone called insulin. But in diabetes, either your pancreas does not secrete insulin or receptors become insensitive to its action. Therefore your blood sugar levels may remain high. To normalize blood sugar levels, your healthcare providers prescribe insulin and medications. 

If you do not take the medications and insulin on time or take in a low dose, your blood sugar levels may remain high- a condition called hyperglycemia. It can be dangerous for your health in the short term, as well as in the long term. 

Blood sugar levels, if remain too high for a long period, can result in complications. Therefore you must monitor your blood sugar levels and keep them under control. If your blood glucose level remains high and does not get controlled with insulin and medications, you may need to get an increment in insulin dose or medications. 

You must visit your healthcare provider frequently if you have diabetes. For regular screening and monitoring for diabetes, you can consult with the Best Internal Medicine Specialist in Karachi.

Retinopathy or eye damage can also occur due to prolonged uncontrolled blood sugar levels. It can damage the blood vessels supplying blood to the retina, eventually leading to blindness. Diabetes also increases the risk of other eye conditions, such as cataracts and glaucoma.
