Five signs which may indicate diabetes

Introduction

Diabetes is a condition in which your blood glucose, often known as blood sugar, is excessively high. Your main source of energy is blood glucose, which comes from the food you eat. Insulin, a hormone produced by the pancreas, aids glucose absorption into cells for use as energy.

Hunger and fatigue: Your body converts the food you eat into glucose, which your cells use for energy. But your cells need insulin to bring the glucose in. If your body doesn’t make enough or any insulin, or if your cells resist the insulin your body makes, the glucose can’t get into them and you have no energy. This can make you more hungry and tired than usual.
Peeing more often and being thirstier: The average person usually has to pee between four and seven times in 24 hours, but people with diabetes may go a lot more.
Yeast infections: Both men and women with diabetes can get these. Yeast feeds on glucose, so having plenty around makes it thrive. Infections can grow in any warm, moist fold of skin.
Nausea and vomiting: When your body resorts to burning fat, it makes “ketones.” This can build up in your blood to dangerous levels, a possibly life-threatening condition called diabetic ketoacidosis. Ketones can make you feel sick to your stomach.
Slow-healing sores or cuts: Over time, high blood sugar can affect your blood flow and cause nerve damage that makes it hard for your body to heal wounds.
