Side effects of three diet pills

There are two views on diet pills now. One view is that weight loss pills are harmful drugs, useful and useless to put aside, anyway, side effects are very large, absolutely can not eat; another view is that although weight loss pills have some side effects, but they definitely work, weight loss diet pills, without diet People who do not need to exercise can still lose weight. Weight loss pills are a shortcut to lose weight.

These two views may be wrong. In the past, when we did popular science, we generally tended to the first viewpoint. It is not recommended to touch diet pills. But weight loss pills are drugs themselves, the key is to see how we use them. The academic community is now becoming more tolerant of weight loss pills. For example, in January 2015, the American Endocrine Society, in collaboration with the European Endocrine Society and the Obesity Association, published “Obese Drug Management: American Endocrine Society Clinical Practice Guidelines”. Inside, for the first time, it was affirmed that weight loss pills can help improve the health of obese patients.

But this is by no means to say that we should turn to the second point of view and have a beautiful illusion about diet pills. For those who are overweight, individuals who have failed to lose weight by conventional methods, for health considerations, weigh the pros and cons, can use weight loss pills under the supervision of a doctor. But for ordinary people, just to pursue beauty and use weight loss pills, it is likely to outweigh the gains.

In other words, diet pills are really a last resort and can be considered for use. Generally, they should not be used easily. This is mainly because most weight loss pills may have some serious side effects. When it comes to weight loss pills, everyone may think that just to lose weight, how much side effects can be

In fact, many weight loss pills were not originally developed specifically for weight loss. They were all used to cure other diseases. It was found that the effect of weight loss became a weight loss drug, which is the same as Viagra. There are many weight loss pills that are initially used to treat psychiatric diseases, as well as treatment of epilepsy, Parkinson’s disease, alcohol addiction (even drug addiction), diabetes, high blood pressure and other diseases. If you think about it, the side effects of these drugs are not small.

Weight-loss pills are also medicines. The market for weight-loss pills requires a strict approval process. Many weight loss pills are allowed to go on the market, but after a while they are banned again, mostly because of side effects.

For example, sibutramine, which we are familiar with, has been very popular as a weight loss drug, but it will significantly increase the risk of cardiovascular disease after use. In the end, it is basically banned in major regions of the world; for example, the appetite-reducing weight loss drug amphetamine And phentermine was widely used as a weight loss drug in the 1990s, but it withdrew from the market because it caused pulmonary hypertension and heart valve disease.

Another example is amphetamine analogs and sympathomimetic drugs, which are generally addictive and have serious risks such as myocardial toxicity and sudden death; ephedrine may cause heart disease, high blood pressure, palpitations, and sudden death; Of chronic pulmonary hypertension with a mortality rate of 50%; limonabant can cause depression and increase the risk of suicide; phenylpropanolamine can cause intracranial bloodstream and stroke, and so on.

Types of diet pills

1. Weight loss pills to suppress appetite

Can reduce your appetite, do not want to eat, thus play a role in weight loss. Such weight loss pills can be said to be mainstream. But the appetite-reducing weight loss drugs generally act on the central nervous system, and the side effects are very large. Many of these weight loss pills belong to psychotropic drugs.

2. Slimming pills to increase thermogenesis

The so-called increase in heat production means that people consume more calories. Such weight loss pills can also be called excitatory drugs, and the targets of action are generally thyroxine and sympathetic nervous system. But strictly speaking, these drugs are rarely used now. Many drugs that increase thermogenesis also have appetite suppressing effects, so these two types of drugs are often not clearly distinguished.

3. Diet pills to reduce calorie absorption

This type of diet pills, orlistat we are most familiar with. Orlistat can inhibit the absorption of some food fats, so that it can play a role in weight loss.

Among the three diet pills, the biggest side effect is the diet pills that suppress appetite. As we said earlier, these drugs generally belong to psychotropic drugs. For example, phentermine, mazindole, bupropion, fenfluramine, sibutramine, zonisamide, amires, rimonabant, and lorcaserin.

Many of these drugs are old weight loss pills, which have been available for a long time, and many of them have been banned on a large scale. However, the domestic weight-loss drug market is very confusing. Drugs banned by drug regulatory agencies may not necessarily appear in a wide variety of weight-loss drug products. Therefore, everyone needs to be vigilant and try not to use it.
