Diet pills are mostly prescription drugs, and it is dangerous to buy and use them without authorization! Diet pills are mostly prescription drugs, which should have appeared on doctors' prescriptions, but look at the ways around us who decided to buy diet pills because of friends' "word of mouth" or magical advertising effects. What's even more frightening is the huge benefits behind diet pills, so that the drugs banned by National Medical Products Administration can still be bought in pharmacies or other channels. Those diet pills that are packaged under the coat of seemingly nutritional products and beauty and skin care products will not indicate what prohibited ingredients are contained at all, so it is really a terrible behavior to use diet pills to lose weight at will. If you are still confused by its seemingly simple appearance, let's look at what you might eat from the physical symptoms after you start eating it! The mechanism of action of the three most common weight-loss drugs The most common weight-loss drugs mainly use three kinds of drugs, one is a drug to suppress appetite, the other is an absorbent to accelerate metabolism and reduce calories, and the other is a preparation to help consume fat and calories. Appetite inhibitors act on the central nervous system to suppress appetite, which has considerable side effects on the body. It is best not to take it without authorization. Accelerate metabolism and reduce absorption, that is, what you eat is not absorbed by the body, or excreted as soon as possible to reduce absorption, reduce the total calorie intake of the body, and achieve the purpose of slimming. Compared with appetite suppressants, the risk is less, but there are still hidden dangers after long-term use. A preparation that helps to burn fat and calories makes you consume the same amount of energy every day, but the consumption is greatly increased. Naturally, it can also play a role in slimming. This is also a drug that acts on the central nervous system and is potentially harmful. 9 kinds of side effects of diet pills were counted. Let's take a look at the bad symptoms after taking diet pills. If you feel that some serious adverse reactions have endangered yourself, you might as well take the diet pills for testing or seek medical diagnosis. Don't ruin your health by losing weight! Symptoms 1: In the process of taking diet pills, there is such a symptom: "After taking diet pills, my stomach is always uncomfortable, bloated and painful. If you always want to go to the toilet, you have to defecate 2 or 3 times a day, and there is a layer of oil in the stool. " Possibility: The diet pills you take may contain Senecio, which is an inhibitor of lipolytic enzymes in the gastrointestinal tract and can reduce the absorption of fat in the small intestine by about 30%. People who like high-fat food use it better. This medicine has less side effects, but the dosage should be controlled. The recommended dosage is 120 mg capsule taken during dinner or within one hour after dinner at the latest. If you don't eat, you don't have to take it. Eat it three times a day at most. Roche is rarely a diet drug approved by the state, which can be used for a long time, but it is best not to use it for more than two years. And taking this medicine will hinder the body from absorbing fat-soluble vitamins. It is recommended to take a multivitamin every day, which can be taken two hours after taking the medicine or before going to bed. In addition, whether this drug is absolutely safe as a diet drug is being evaluated. Therefore, it is not recommended for children under 18, pregnant women and lactating women. Symptom 2: In the process of taking diet pills, there is such a symptom: "I used to be a sleepy person, but I just took this diet pill for two days, and I found that I was very excited every night. I don't want to sleep, and I can't sleep in bed. I eat less than before and am full of energy! " Possibility: The diet pills you take may contain amphetamines. At first, taking this medicine has the above effect, but with the emergence of drug resistance, there will be symptoms such as emotional instability, delusion, hallucinations and sleep disorders. Moreover, amphetamines are as addictive as drugs. Once addicted, the process of withdrawal is very painful, and even symptoms such as anxiety, depression, fatigue, drowsiness and overeating may appear. Experts suggest that this medicine should never be taken easily. Symptom 3: In the process of taking diet pills, this symptom appears: "I have been taking diet pills recently and my appetite has become very poor. I can't eat, and my weight has dropped, but I feel dizzy, headache, drowsiness and even some palpitations. What's wrong? " Possibility: The diet pills you take may contain Fenfen. Fenfen is also an appetite suppressant, and one of its main components is Flaaming. 1September 1997, the US Food and Drug Administration officially banned the use of Fenfen to lose weight. This is because the sales of diet pills containing Fenfen have been very high for more than a year, but at the same time, it has also brought high side effects, and even problems such as heart valve damage and pulmonary hypertension may occur after long-term use. The popularity of fenfen in China is far less than that of its main component, Flaaming. Although Fen Flaaming has been established as a prescription drug, even banned by the state for weight loss, if you pay attention to the small pharmacies around you, you can buy this small white pill-Fen Fla Aming, a psychotherapeutic drug, which is sold as the most economical weight loss drug without any prescription and at almost no cost. What harm does it bring? Who should pay the bill? Symptom 4: In the process of taking diet pills, this symptom appears: "I ate this diet pill brought back from abroad by my friend, and I felt dry every day, and my lips cracked the next day. Moreover, I have a headache, I can't sleep at night, and my heart seems to have accelerated a lot! " Possibility: The diet pills you take may contain sibutramine. The principle of this medicine is to suppress appetite by inhibiting the reabsorption of nerve conduction substances. Because oral absorption is good, it can have obvious weight loss effect within 6 months, which was once popular in Europe and America. But recently, New Zealand's key drug monitoring department found that this diet drug may damage people's memory. There are also data to prove that this ingredient not only affects memory, but also causes other cerebrovascular problems, such as confusion, dizziness and visual abnormalities. Symptom 5: In the process of taking diet pills, this symptom appears: "After taking this diet pill, I am a' sleeping cat'. I can't sleep. My lips are always dry. I feel very tired, and I pee a lot without doing anything. " Possibility: The diet pills you take may contain another common appetite suppressant-PPA. This name has been "notorious" in the field of cold medicine. In order to draw a clear line with it, some cold medicines even indicate directly in their product advertisements that they do not contain PPA. PPA can cause stroke in women. Symptom 6: In the process of taking diet pills, this symptom appears: "After taking this diet pill, I feel unbearable abdominal pain in a short time. I spent most of the morning in the toilet, just like eating my stomach. I vomited once at noon and felt weak and even a little dehydrated. " Possibility: The diet pills you take may contain laxatives such as senna. Experts pointed out that "laxatives" are not diet pills in clinical medicine, but they are often misused or abused as diet pills because they can reduce the time of food staying in the gastrointestinal tract and the probability of being absorbed. If laxatives are not used properly, they will also bring quite serious consequences. Take Senna as an example. Many people think that it is a pure natural herb, and it has no side effects when used to lose weight or treat constipation. In fact, this is a completely wrong view. Improper use of senna leaves may cause abdominal pain, nausea and vomiting. Severe cases may even induce upper gastrointestinal bleeding, menstrual disorder in women, and even some people are addicted to taking senna. After stopping taking senna, it will not only make constipation more serious, but also lead to withdrawal symptoms such as anxiety, insomnia and general malaise. Symptom 7: In the process of taking diet pills, there is such a symptom: "After taking this diet pill, I always feel bloated and have a stomachache." Possibility: The diet pills you take may contain glycoprotein (acarbose). Tang Lu tablets can lower blood sugar, and the liver enzymes in the blood of drug addicts will increase. Some people died of hepatitis while taking Tang Lu tablets. Although the correlation between Tang Lu tablets and hepatitis has not been confirmed, we should not take it lightly. Symptom 8: In the process of taking diet pills, this symptom appears: "After taking diet pills, my most obvious feeling is that I have too much urine, and then I feel weak and sometimes even dizzy. The doctor said that my blood pressure is low. " It's possible: the diet pills you take may contain some diuretics. Diuretics are generally used for diuresis and lowering blood pressure. A large amount of urine in the body can naturally make the body temporarily lose weight. Therefore, diuretics are often added to diet pills or tea. But diuretics, as the name implies, reduce water in the body, which is not really weight loss at all. Symptom 9: In the process of taking diet pills, this symptom appears: "After taking this diet pill for a period of time, I found that I began to lose sleep, sometimes I felt dizzy for no reason, and even felt flustered and uncomfortable!"
