Diabetes

Updated: Oct 25, 2020

There are four types of diabetes: type 1, type 2, prediabetes and gestational diabetes (during pregnancy). These types of diabetic conditions are different from diabetes insipidus which causes excessive urination. Type 2 (diabetes mellitus) is mostly influenced through a person’s lifestyle but it is also passed through hereditary so it is very crucial for children of diabetic parent(s) to have a healthy lifestyle to reduce their risk of developing it. It is a condition in which either insufficient insulin is produced or the body resists the effects of insulin. Now insulin is a hormone which helps regulate blood sugar level in our bodies therefore a person suffering from diabetes will have higher blood sugar level than normal. In prediabetic condition, the blood sugar levels are high but enough for a person to be diagnosed as diabetic. Usually prediabetic and gestational conditions are easily reversible through diet and exercise followed by type 2 which has better chances to be cured if diagnosed early but type 1 is an autoimmune disorder which is incurable. Below is a chart in which difference in blood sugar levels in milligram per deciliter (mg/dL) of a healthy individual are compared with a diabetic person.



Symptoms of type 2 diabetes:

  1. Blurry vision.

  2. Slow healing of wounds.

  3. Polyuria (excessive urination).

  5. Polydipsia (excessive thirst).

  6. Lethargy.

  7. Tingling, numbness or pain in hands or feet.

  8. Unintended weight loss.

  9. Dark skin patches.

  10. Itching and yeast infection.

  11. Loss of sex drive and erectile dysfunction.

Complications of type 2 diabetes:

  1. Retinopathy: loss of vision.

  2. Neuropathy: damaged nerves.

  3. Nephropathy: damaged kidneys.

  4. Diabetic foot: slow healing of injuries on feet.

  5. Loss of hearing.

  6. Cardiovascular diseases.

  7. Depression and/or dementia.
