They asked me that. I explain. Can. Just not quite the way it is presented.
There are different situations when someone does not have enough food. But now if this happens, then people are more likely to starve themselves. Anorexia nervosa and similar diets.
From this, people quickly lose weight, and their heart also loses weight. But do not think that if you starve for four days, you will die of cardiac arrest. This usually does not happen.
When a person eats little, his muscles lose weight. Including the heart muscle. The heart will become smaller and will react poorly to physical activity, but it will still maintain decent performance for a very long time.
People who are hungry usually have a slower heart rate. It is clear that if a person does not have muscles, and does not have the strength to use these muscles, then the heart does not need to pump a lot of blood. Therefore, among the starving, the heart beats less and less.
In patients with anorexia nervosa, the heart gradually slows down, and when the pulse reaches 40 or less, then this is a sure sign that the hospital will not do without.
In general, for anorectics, the heart rate can easily drop to 25 per minute. If this happened to any other person in the hospital, he would be immediately sent to intensive care.
But with anorectics it happens, and they even sit quietly at home without any resuscitation.
The fact is that they lose weight gradually, and the needs of their organisms also slowly decrease. They don't run or jump. Therefore, they gradually get used to it and can live for a long time with a minimum heart rate.
And of course, everyone understands that if you lose weight enough, you can die unpredictably from any heart rhythm disturbance, infection, or from the fact that different internal organs begin refuse.
