1. Diarrhea leads to dehydration and thirst after taking medicine.

Many diet pills contain laxatives, such as rhubarb and senna leaves, which will reduce the time of food staying in the gastrointestinal tract and the chance of being absorbed. When people have severe diarrhea or long-term diarrhea, a lot of water and inorganic salt ions in their bodies will be lost, so they will feel thirsty.

2. The thirst caused by water absorption is suppressed.

The principle of many diet pills is to decompose human body water and inhibit water absorption in order to achieve the purpose of losing weight. So sometimes even if you drink a lot of water, you often feel thirsty because your body doesn't absorb it.

3. The acceleration of fat metabolism is due to the absorption of body water.

Diet pills contain ingredients that accelerate the burning and decomposition of body fat, and water participates in all metabolism of the body, so the burning and decomposition of fat will be accelerated, and the loss of water will be accelerated, which will easily lead to thirst.

Another: Do you take diet pills to quench your thirst by water or fat?

Mainly moisture.

After taking diet pills, we can lose weight in a short time, but we don't lose fat. Fat density is low. If a person really loses 10 kg of pure fat, his body shape will change greatly. However, if you lose weight 10 kg on diet pills, your body shape has not changed. That's because the 10 Jin of fat lost is very little, or even no fat, so diet pills can't reduce fat, but most of them lose water.

Most of the diet pills on the market have added prohibited ingredients, so it is particularly important to choose a safe and effective diet pill.
