Food, sex and mental anguish
Suppose you are a woman and your menstruation suddenly stopped (although there is no pregnancy). This happens on the background of oral contraceptives, and without them. When you finally get to the gynecologist, he will naturally send you to various studies to make sure that nothing really bad happens to you. But at the same time, the doctor will ask you how much you have recently been nervous and worried and whether you can somehow rebuild your life in order to stop this outrage, reduce the level of stress hormones, restore the normal synthesis of GnRH and regain your monthly bleeding - at least as a marker of overall body well-being.
Maybe worse: let's say you're a man. The good news is that from stress you most likely will not stop standing. In articles about erectile dysfunction and psychological problems, quite a lot is said about depression, but not about stress per se; in one of the studies they tried to establish a link between stresses at work and the quality of erection, but nothing statistically significant was found. The problem is different. In the case of constant stress, men can have sex, but do not want to - libido decreases. In addition, the concentration of sperm in the ejaculate falls (the same happens in the case of one-time, but severe stress). These effects are associated with a decrease in the level of luteinizing hormone and, probably, testosterone.
But the most unfortunate option is if you are pregnant and experiencing stress. In principle, progesterone, which is abundant during pregnancy, has a calming effect and can prevent the development of stress reactions, but sometimes life is so hard that it does not cope. If we take pregnant laboratory mice and make them listen to loud unpleasant sounds, then the embryos can disappear altogether, dissolve in the uterus. People have no such effect, but miscarriage or developmental disorders are possible.
In the suppression of reproductive function, many stress hormones are involved in varying degrees - adrenocorticotropic hormone, cortisol, and adrenaline are involved in the process of reducing the synthesis of sex hormones. But the key role seems to be played by the very first hormone of the stress reaction - corticoliberin, which is secreted in the brain (in the hypothalamus) and also affects the brain (the pituitary gland), triggering the whole further cascade of stress hormones. Literally in the last ten years, it turned out that corticoliberin receptors are not only in the pituitary, they are scattered throughout the body, in particular, there are many of them in the male and female reproductive systems. It seems that both the ovaries, the testes, and the placenta themselves are able to produce a small amount of corticoliberin for self-regulation - and they can also react to this hormone, which came from the hypothalamus and carries an unequivocal signal: ".
During acute stress, we are not only not to love, but not to food. The activation of the sympathetic nervous system and the release of adrenaline sharply suppress appetite, both due to the direct effect on the gastrointestinal tract and due to an increase in the level of glucose in the blood. Numerous experiments have shown that artificial disruption of the sympathetic nervous system causes experimental animals to eat very much, and the increase in its activity inhibits food intake23. Hormones involved in the early stages of stress inhibit the activity of the upper gastrointestinal tract, but they increase the motility of the lower regions. That is why diarrhea can begin from severe fright. In everyday life, this is called “bear disease” - non-authoritative sources say that the term originated from the attack of large groups of hunters on a sleeping bear in a den. To wake the bear, and then kill him, while he was just awake and not thinking well, they made a big noise. Allegedly, while the unfortunate animal woke up with severe diarrhea, and while it tried to clean the intestines, the hunters came closer and killed him. Looks like hunting is a dirty job!
But short-term fright passes, and hormones associated with the later stages of the stress reaction, primarily cortisol, remain in the body. At this stage, stress can, on the contrary, increase the appetite (which is logical: the immediate danger has passed, now it is necessary to restore wasted resources). There are two interesting features: first, it seems that after stress women experience greater hunger than men. Secondly, stress provokes people not only to eat more, but to choose the most tasty (that is, high-calorie, fatty, sweet and salty: our brain believes that food that is rarely found in nature represents the maximum value for us).
