Why do people swell up after they die, and why do people swell before they die

Generally speaking, people do not swell up after death. If you die from a general disease, you will not get swollen, if the person has uremia before death.

or liver function.

It's not good to wait for diseases. It may swell up. Because if the kidneys are not good, it will lead to edema all over the body, this is possible, when we find that the body is swollen for no reason, we must press it, if he can bounce up immediately, it will be with kidney disease.

It does not matter. If it is difficult to play it down, it may be kidney disease, because only people with kidney disease may have edema, and other diseases generally do not.

I am a forensic doctor, that is, a forensic doctor who goes to the scene of an unnatural death and examines the body, and if I find the body of an unnatural death in my work, I usually go to the funeral home autopsy room if I conduct an autopsy. The body was also transported by funeral home staff, who usually wrapped the body in a black body bag and pulled the handle of the body bag with their hands. If it was a building, there was no elevator, and the deceased was very fat, and four people could lift them, and they would be tired and sweaty and panting.

Sometimes when describing things as heavy, they will say "dead and sinking", so many people will have a direct impression that people will become heavy after death? In fact, it is not like that at all, and it does not conform to the laws of science in the real world. As a medical examiner, let me explain.

A person does not gain weight because of death, in fact, the moment of death is almost no different from the moment of death. Some people even study whether people have a soul after death, that is, the weight after death - the weight before death = the weight of the soul, and some people even measure the weight of the soul as 21g. If the soul has weight, and the soul soars after death, then the weight of the person should be reduced.

But if you lift the corpse, why does it feel like weight gain? You can do an experiment, if you hold a 30-kilogram child and a 30-kilogram bucket of water, which one will feel lighter? I think it's a lot lighter to hold a child.

Why does bottled water feel heavier for the same weight? Because the child is alive and the bottled water is "dead", which is why the dead are considered to be sinking, the principle is the same.

When a person dies, the body is in an absolute static state, while a living person will not, for example, if you pull a living person, the living person may unconsciously exert muscles, while the dead person will never exert force, and all the weight of the corpse will act on the person who pulls him, so it will feel very heavy. This is why it creates the illusion that the dead are heavier than the living.

After death, because the circulation stops, the oxygen concentration in the blood is low, so it will turn purple, and because of the ischemia and hypoxia of the tissue cells, degeneration and enlargement will occur. Opinions and suggestions: The primary cause of human death is different, the lesions of the heart, liver, lungs, kidneys, and brain of the important organs before death are different, but the final result is respiratory arrest, heart arrest, brain death, death is the natural law of life, so we must cherish life and accept the facts, treat ourselves well, and treat everything well.

Most of the elderly will have symptoms of edema of the lower limbs and even the whole body before dying, mainly due to the following reasons: 1. Most elderly people cannot eat before dying, resulting in anemia and hypoproteinemia, hypoproteinemia can cause a decrease in plasma colloidal osmotic pressure, so that the water in the blood vessels seeps out to the outside of the blood vessels, and these excess water will gather under the skin, and it is easy to gather in the lower limbs, sacrococcygeal and other sunken parts of the body, so there will be swollen feet; 2. The elderly before dying are delirious, unable to move, and the blood circulation of the lower limbs is not smooth, which leads to the reduction of venous blood return in the lower limbs, and the symptoms of swollen feet; 3. Severe heart, liver and kidney diseases can also cause edema of the lower limbs; 4. The dying elderly are bedridden for a long time, which is easy to cause deep vein thrombosis of the lower limbs, which leads to swollen feet.

Causes of edema before death:1It is caused by the cessation of blood circulation.

2.It may be caused by a lack of blood power in the cardiovascular system. In this case, you may also experience dizziness and weakness, or your appetite may decrease and your face will be pale, so if you want to eat anything when you can eat now, you must eat more and observe your condition.

Cancer patients have a very large impact, and may also cause symptoms of edema in the lower limbs, some patients if they do not pay attention to reasonable physical care, it may also lead to other complications, and even lead to the harm of death in a short period of time.

After death, the body's cells appear edema, necrosis, and some will also produce gas, which will be swollen.

Thank you for the trouble to adopt!
