What is diabetes ? What are its symptoms ?
✓

Answer

Diabetes $–$ It is a disease caused by lack of the hormone insulin secreted by pancreas. A small group of cells called Islets of Langerhans in the pancreas manufacture insulin. When these cells do not produce enough insulin, the body can neither use sugar nor store it in liver in the form of glycogen.
The blood contains extra sugar but other body tissues lack it. The level of sugar in the blood rises to such an extent that some of it is passed out along with urine. The symptoms of diabetes include excessive thirst, frequent need to urinate, fatigue and loss of weight.
