First, people's weaknesses are often accumulated over time. It takes some energy to digest food itself. If you don't have enough energy, you won't be so energetic, and then you won't eat food too actively. This is what the saying goes, poor appetite (this phenomenon is obvious when you are sick). The above situation is easy to form a vicious circle, that is, when the human body is weak, the food intake decreases, and when the food intake decreases, people tend to be weak. Over time, the weakness of the human body is clearly reflected.
Second, the same food affects everyone differently. We often hear that we should eat more of this and that, which is only true with great probability, but it is different when it comes to individuals. For example, some people will have an accident if they eat soft-shelled turtle or soft-shelled turtle, but most people have no problem eating soft-shelled turtle or soft-shelled turtle. This is the difference; Some people have problems eating shrimp, but most people have no problem eating shrimp, which is one of the differences. But people who can't eat turtles don't have to eat shrimp; Similarly, people who can't eat shrimp don't have to eat soft-shelled turtle. These are extreme differences. In fact, food affects everyone to varying degrees, but we don't realize the differences between everyone, but our bodies are aware of these differences, and these differences will be manifested in everyone's physical strength. A big family, brothers and sisters, all eat the same food, but their bodies are different, and some are even very weak and thin, which is probably caused by the different effects of food on everyone.
The second point mentioned above is that the food efficiency of different people is different for the same kind and quantity of food, so some people eat less and are healthy, while others eat more and are not strong. This situation is generally misunderstood as poor absorption or poor digestion of the body. In fact, the type of food is not suitable for a specific individual. He must choose the right food for himself.
There are many reasons for physical weakness, not all of which are caused by poor appetite.
Similar to the poor power of a car, it is not necessarily caused by lack of fuel, and people's weakness is not necessarily caused by a small appetite.
The power of the car is not good, the lack of oil is one reason, or it may be that the car has a small displacement and is inherently weak; It may also be that the power is ok, but driving at low speed for a long time in the urban area leads to excessive carbon deposition and incomplete combustion.
Therefore, the weakness of the human body is partly caused by poor appetite. The common situations are as follows:
1. The human body has poor absorption function. Many friends eat a lot, but they often have diarrhea, poor nutrition absorption, thin, slender, prone to hypoglycemia, sweating when they are tired and hungry, and naturally feel weak.
2. Abnormal metabolic transformation. Human liver is an important organ for substance transformation and synthesis, among which albumin is an important organ. After the reduction of human albumin, people will be very tired, weak and listless. This is often the case for patients with hepatitis B and liver cirrhosis in hepatology department. Most of the patients' friends are pale (black and yellow) and thin.
3. Metabolic dysfunction. For example, friends who eat more and exercise less are often sleepy and may fall asleep at a red light; Dozing off on the highway; Eating it is like pulling my muscles out. This seems to be "weak" to ordinary people, but it is actually a manifestation of metabolic syndrome such as hyperlipidemia, hyperglycemia and high blood viscosity. In the words of Chinese medicine, it seems that most of them are too humid. If accompanied by fear of heat, sweating, head oil and greasy face, it is mostly damp and hot.
4. Cardiac insufficiency. Cardiac insufficiency, some people used to call it heart failure. This kind of patients can't meet the needs of the whole body because of the decline of heart strength, and their physical strength is very weak. He will be tired out with a little activity, such as taking a few bites of rice, putting on clothes, lying down, walking to the toilet and saying a few words. When I was an attending doctor in the geriatrics department, several old friends were like this. In the traditional Chinese medicine system, most of them are in the state of heart-kidney yang-qi failure, often accompanied by edema and other insoluble body fluids.
. . . . . .
In fact, there are many kinds of patients with clinical weakness, and the reasons are also very different. Don't think that only how much you eat determines whether you are weak or not.
The human brain naturally likes to simplify problems for its own understanding. Although this is an advantage and helps to grasp the key points quickly, it is easy to make simplification mistakes in the face of complex systematic and multi-level problems.
Medicine is a complex and systematic subject with many unknown fields. The complexity of many knowledge systems is far from common sense speculation. It often needs systematic and complete thinking, such as solving the clinical reasoning of a case, and it needs professional doctors with perfect knowledge structure and extremely rich clinical experience to make relatively accurate judgments.
People's weakness is not caused by a small appetite, but by a small appetite. People who generally eat less are physically weak.
There are few congenital factors and acquired reasons for appetite, and some diseases can also lead to decreased appetite.
Thank you for your question and answer invitation ~ ~ ~
Eating less is bound to make people weak. All kinds of vitamins, energy, protein and fat needed by human body are obtained from food. Eating less means that the supplementary nutrition is not enough.
There are two main reasons for physical weakness:
One is congenital deficiency, which is influenced by genetic factors;
The other is excessive consumption the day after tomorrow:
For example, all kinds of overwork, unclean diet, bad mood and so on Or the consumption of diseases caused by it. Therefore, people in the past paid great attention to health preservation, while we modern people have great pressure on life, changed living habits and lacked necessary exercise, leading to physical weakness.
Beckham thinks that according to his specific physical condition, if possible, he should go to the hospital to check what causes it, and then solve it symptomatically ~ ~ ~
Mainly malnutrition.
The weakness of human body is not determined by the amount of diet, but by the metabolism of internal organs. Just like a running machine, the inside of the machine is full of parts of different shapes, large and small. If one of the parts is badly worn, the machine will run abnormally. When one of our internal organs is diseased, then its metabolism will have problems. When the quality of its metabolic cells is not enough, then bacteria will invade, erode the nuclear lesions inside and destroy the active cell tissue inside. When there are more invading germs, then this organ will be diseased. When healthy active metabolism declines, people's qi and blood will lose money, and the deficiency of qi and blood will directly affect people's weakness. Therefore, the weakness of human body is not directly proportional to the amount of food you eat. Without good internal organs, it is useless to eat again.
In fact, weakness and poor appetite are interrelated and influence each other. If the spleen and stomach are weak, there is naturally no desire to eat; If you eat less and don't want to eat, the digestive function of the spleen and stomach will become weaker and weaker, because it doesn't take much effort to digest your food. So the two affect each other.
However, eating less is one of the many factors that lead to human weakness, and there are many other factors, such as depression, overthinking, spleen and stomach inflammation and so on.
So for patients who are usually weak and have a small appetite, my advice is:
Eat as much as possible at every meal (not to make you full), chew slowly, think less, exercise properly every day, consume calories and fat in your body through exercise, and then eat more.
Serious cases can only rely on drugs, such as: ginseng Jianpi pills, pepsin granules, qi and blood and capsules.
Of course, some people are related to congenital constitution. They eat less and their bodies are empty. There is really no good way except to exercise more by yourself at ordinary times.
The feeling of human weakness usually appears after the initial recovery from a serious illness or a long illness, and will gradually improve after conditioning. If a person is sick and weak for a long time, he should go to the hospital to have a check-up and see what the reason is before he can prescribe the right medicine.
People with weak constitution are not caused by small appetite, but by congenital deficiency or acquired diseases, which will affect people's appetite. A small appetite will lead to further physical weakness, but it can also show that physical weakness is caused by a small appetite.
People with weak constitution should make scientific supplements, increase nutrition, exercise moderately and enhance their physique.
