Low blood sugar: What are the effects in our body


Fig. Effects of low blood sugar
Every cell in your body needs sugar (glucose) to function. When your blood sugar levels drop too low, your cells become starved for energy. Initially, that can cause minor symptoms, but if you don’t get your blood sugar levels up soon, you’re at risk of serious complications.

Effects of Low Blood Sugar on the Body

When your blood sugar (glucose) levels fall below the normal range, it’s called hypoglycemia, or insulin shock.

Low blood sugar can happen when you skip a meal. It can also happen if your pancreas releases more insulin than it should after you’ve eaten. The most common reason for low blood sugar is diabetes. In type 1 diabetes, the pancreas can no longer produce insulin. In type 2 diabetes, the pancreas doesn’t make enough, or your body can’t use it properly. To keep blood sugar levels from rising too much (hyperglycemia), you need the right amount of insulin. With
insufficient insulin, your blood sugar levels rise. Too much, and your blood sugar levels can plummet.

As calcium (Ca2+) is one of the main components of our bones, large amounts are present

Bone Metabolism: Bone formation and bone resorption (Part 1)


BONE FORMATION AND BONE RESORPTION

Fig. Bone Cells
Living bone is constantly being remodeled. The state of our bones is always close to an equilibrium between bone formation and bone resorption. In childhood and during the teens, bone formation is slightly ahead. We reach peak bone mass in the twenties, and from then onwards, resorption has the upper hand. There are two reasons for the

Chemotherapy and it's side effects

Chemotherapy side effects
Chemotherapy drugs kill cancer cells, but they can also damage healthy cells. This damage to healthy cells causes side effects. Different cells and tissues in the body tolerate chemotherapy differently. Chemotherapy drugs have the greatest effect on rapidly dividing cells, such as blood cells in the bone marrow, cells lining the mouth and gastrointestinal (GI) tract and hair follicle cells.

What causes side effects?
Cancer cells tend to grow fast, and chemo drugs kill fast-growing cells. But because these
