What are the hazards of diet pills? The principle of action of diet pills can be divided into three types: absorbent to suppress appetite, accelerate metabolism and reduce calories, and preparation to help consume fat and calories. I sorted out the relevant information according to this question, hoping to help you.

The harm of diet pills:

1, can't sleep -PPA

Symptoms: Hà Thu became a "sleeping cat" after taking diet pills. She can't wake up and her lips are always dry. She looks in a trance every day and feels particularly tired after doing nothing.

Analysis: The diet pills taken by Hà Thu may contain PPA. This drug is also a common appetite suppressant. PPA is usually added to cold medicine, and excessive intake of PPA by women can lead to hemorrhagic stroke. In addition, PPA will also have adverse effects on cardiovascular and cerebrovascular diseases, central nervous system and gastrointestinal system.

2, can't sleep at night-* * * * * methaqualone * * *

Symptoms: Qian Lan used to be a sleepy, but after taking diet pills, he was very excited at night and didn't want to sleep, so he couldn't sleep in bed. She ate less than before, but she still looked full of energy.

Analysis: The diet pills taken by Gan Lan may contain * * * * Aprotan * * *. When you first take this medicine, you will have cyanosis symptoms.

However, once the body is resistant to * * * *, patients will have emotional instability, hallucinations, sleep disorders and other symptoms. Moreover, * * * is as addictive as * * *. Once addicted, the process of withdrawal is very painful, and even symptoms such as anxiety, depression, fatigue, drowsiness and overeating may appear. Women had better not choose diet pills containing * * * ingredients.

3, don't want to eat-Marat safin * * Ian safin * * *

Symptoms: After taking diet pills in Xia Bing, her appetite became poor, she couldn't eat anything, and her weight also dropped. At the same time, she felt dizzy, headache, drowsiness and even palpitations.

Analysis: The diet pills taken in Xia Bing may contain fenfen ***Ian-phen***. Fenfen is an appetite suppressant, and one of its main components is fenfenfenamine * * * lanfluramine * *.

1Since September, 1997, the US Food and Drug Administration has banned the addition of Fenfen to diet pills, because the diet pills containing Fenfen have great side effects, and long-term use will bring heart valve damage and pulmonary hypertension to users. Fenfen and Fenmin are also restricted as prescription drugs in China.

4, often go to the toilet-Roche fresh ***xenical***

Symptoms: Erzhen took diet pills. I always feel uncomfortable, bloated and painful. I always want to go to the toilet and have to defecate 2 ~ 3 times a day. There is still a layer of oil in my stool.

Analysis: Erzhen's diet pills may contain Roche's fresh Seneca. This medicine can reduce the absorption rate of fat in the small intestine. Roche is rarely a product approved by the state for listing. This medicine has less side effects and is more suitable for women who get fat because they often eat high-fat foods.

Although Roche fresh food is listed with the approval of the state, whether it is absolutely safe to add it to diet pills is still under evaluation. It is generally believed that the dosage of drugs should be controlled and the use time should not exceed two years.

Roche should rarely take it at meals or within one hour after meals, each time 120mg. If you don't eat, you don't have to take it. Eat it three times a day at most. Because taking this medicine will affect the body's absorption of fat-soluble vitamins, it is necessary to supplement appropriate vitamins every day during taking Roche Fresh. Vitamins can be taken within two hours after taking Roche fresh or before going to bed. Pregnant women, lactating women and children under two years old had better not take Roche fresh.

5. Dry mouth-sibutramine * * * sibutramine * * *

Symptoms: Qing Xue took the diet pills brought back from abroad by her friends and felt thirsty every day, so she had to drink a lot of water. On the second day after taking this medicine, Qing Xue not only suffered from chapped lips, but also symptoms such as headache, insomnia and rapid heartbeat.

Analysis: Diet pills in Qing Xue may contain sibutramine * * * sibutramine * *. The principle of this medicine is to suppress appetite by inhibiting the reabsorption of nerve conduction substances. Diet pills containing this ingredient have been very popular in Europe and America because they can be well absorbed by the human body and have a remarkable weight loss effect.

Recently, however, it has been found that diet pills containing sibutramine will not only reduce people's memory, but also cause many cerebrovascular diseases. In the early stage of this disease, people will show confusion, dizziness, headache and visual abnormalities.

6, insomnia and palpitations-* * *

Symptoms: Cuiwei began to suffer from insomnia after taking diet pills, and sometimes she felt dizzy and flustered inexplicably.

Analysis: Cuiwei's diet pills may contain * * *. * * * can act on the central nervous system and promote the consumption of body heat and the decomposition of fat. However, it has recently been found that the potential danger of * * * is higher than its weight loss effect.

* * * is a kind of A and B receptor stimulant, which has great side effects on the heart and central nervous system. Therefore, women with hypertension, coronary heart disease, hyperthyroidism, glaucoma and prostatic hypertrophy should use * * with caution. If women abuse * * * for a long time, it will also cause a reversal reaction, secondary vasodilation and dependence on this diet drug.

7. Vomiting and diarrhea-laxatives

Symptoms: After Lulu took the diet pills, it didn't take long for her stomach to feel unbearable. She stayed in the toilet all morning and vomited once at noon, feeling weak and even a little dehydrated.

Analysis: "laxatives" are not diet pills in clinic, but they are often added to diet pills because they can reduce the time of food staying in the gastrointestinal tract and reduce the absorption probability of nutrients.

If women can't use laxatives correctly, it will have quite serious consequences. Take Senna as an example. Many people think that it is a pure natural herb, which can be used to lose weight or treat constipation. Actually, this is a wrong view.

If Senna leaves are taken improperly, it may cause abdominal pain, nausea and vomiting. In severe cases, it may induce upper gastrointestinal bleeding, menstrual disorder in women, and even make users addicted, which will not only aggravate constipation, but also lead to withdrawal symptoms such as anxiety, insomnia and general malaise.

8, stomach pain-sugar gourd ingot

Symptoms: Xiaoyan always feels bloated and a little painful after taking diet pills.

Analysis: Xiaoyan's diet pills may contain lozenges, which have the effect of lowering blood sugar. After people take this diet pill, the liver enzymes in their blood will increase. Some people may get hepatitis or die from it when taking pills.

Although the exact relationship between lozenges and hepatitis has not been confirmed, the danger of lozenges is beyond doubt.

9, low blood pressure-diuretic

Symptoms: After taking diet pills, Zi Xuan obviously felt too much urine, and then he felt weak and sometimes even dizzy. According to the doctor's examination, Zi Xuan suffers from low blood pressure.

Analysis: The diet pills taken by Zi Xuan may contain diuretics. Diuretics are generally used for diuresis and lowering blood pressure. When a large amount of water in the human body is excreted with urine, people's weight will naturally drop, so diuretics are often added to diet pills. But taking diuretics is the loss of water in the human body, not fat.

So far, the medical community generally believes that there is no drug in the world that can effectively lose weight without any harm to the human body. It's best for women to face the overwhelming advertisements of diet pills rationally. Even if you choose diet pills, you should take a good look at the drug instructions to avoid the harmful drug ingredients mentioned above.

Above, I shared the harm of diet pills for everyone. Friends who take diet pills should pay attention!
