Hello! I work as a doctor for 21 years. My name is George O. Sapego. This article will tell you about the normal aging process.
All are aging. At the age our body accumulates errors, problems, and something starts to work worse than before. We become susceptible to certain diseases. Much depends on heredity.
Why grandmother lived in '94
In Denmark, a study was carried out [1], which found that the duration of life only 25% dependent on genetics and 50% of the external factors.
True humans all depends primarily on genes over 90 years. So that story about the grandmother who ate what she wanted, and lived to be 94 years - this is nonsense. Grandmother lived in spite of life and because of their heredity.
biorhythms
In our internal clock with age begins rassinhron. Hormones are allocated is not so smartly disturbed sleep, appear strange fluctuations in body temperature.
Elderly difficult to adapt to the change of time zones and seasons. This is normal.
People with age in normal gradually lose their liveliness. This means that they have slower and smaller dispersed within the heart and blood pressure. Ears do not hear such a wide range of sounds. And to stress the elderly react too slowly.
Many of these things can actually train. Older athletes sometimes disperse and slow down your heart almost as much as the young. [2]
fragility
With age, the body's reserves are gradually being depleted. Eventually this leads to the so-called age-related fragility, when all the power goes only to the maintenance of life. [3]
Such old softly shuffling in one mode, and any traumatic event instantly knocks them out of the rut. They can easily begin to thunder in the hospital or even die.
Sometimes it happens that people are not dying, but simply give up, start to navigate in bad conditions, they go under him and all that. That is completely relaxed and the brain is no longer solve the problems can not be.
When I explain this to relatives of elderly patients, some people do not understand. They think that the old man badly treated in the hospital.
In fact, when a grandparent get to the hospital with a heart attack is not even, as, for example, pyelonephritis, they have only one infection and the forces leave, and then nonsense begins. It's not an insult, it's just with muscles weakened brain. The usual thing.
Blood
Blood is more or less normally produced and recovered for a lifetime.
Bone marrow, which produces blood cells, with age gradually replaced by fat. So to become a bone marrow donor has not come out. And if you suddenly feel an urge to do chemotherapy, the old bone marrow die faster.
With age, the bleeding time is usually increased. Platelets, which stick with holes in the vessels in the elderly no longer becomes. But these platelets become very nervous and for any reason, seek to arrange thrombosis [4].
Digestion
Gastrointestinal tract with age works more or less normally. Old people are usually to the death have the energy to digest food.
With age, the gums slowly recede, exposing the necks of the teeth, and the ports.
Salivary glands produce less saliva (I have an article about it). It is well-known story.
Not everyone knows that the elderly poor food passes from the throat into the esophagus. This is due to the muscles.
Watch what happens - bad teeth chew on pieces of food, saliva little slow food goes into the esophagus. What do you think, what is it predisposes? Right! Old people often poperhivayutsya and choke.
There's still an interesting age-related changes occur in the esophagus. Muscles it may become thicker than the young. This esophagus can not do normal wavelike contractions. If it flew of gastric acid, it is not washed off long back [5].
The interesting thing with the esophagus called presbiezofagus (Senile esophagus). It went from presbyopia, which is called presbyopia.
In the case of sealed and can not adapt to the presbyopic eye lens. People with such farsightedness see neither distant nor near. That's esophagus in the elderly, too, becomes dense and can not normally be reduced.
There's so much more interesting in this field of medicine. If you like, write in the comments.
