Contemporary people often stay up late and go to bed late under the pressure of daily heavy life, usually sleeping late in the morning, but also hurrying to pack up to go to work and class, and many people have developed the habit of skipping breakfast.
I have to spend the morning hungry, sometimes because I am busy and I don't have time to eat lunch, or I can simply deal with it with instant noodles.
We all understand that irregular eating is not a good habit, and daily work and study, especially those with high intensity of mental work, need to consume a lot of energy every day.
Some people will have many adverse reactions when they are hungry, trembling hands and panic.
So let's take a look at the real cause of hunger and trembling.
First, the real reason for the panic and trembling when you are hungry
Hand tremor generally refers to the involuntary tremor of the hand, and movement requires a certain amount of power, that is, muscles, and nerves are responsible for issuing instructions to muscles.
The problem of trembling may be related to these two links, such as Parkinson's disease, cerebellar disease will cause the frequency of nerve instructions to become higher, and will begin to tremble, this situation is like the command (nervous system) is invaded.
There is also a possibility that the command is normal, but there is a problem with the executor (muscle), you do not give food, how can people still work? This is the case with hunger.
In addition to pathological palpitations, insufficient energy is also an important cause of panic.
Heart beats mainly rely on the contraction of the heart muscle, as a 24-hour non-stop great organ, each heart beats need to consume a lot of energy, energy supply is not available, no matter how competent it is, it has to strike.
Let's take a look at why energy is out of supply.
The most important part of the food we eat is sugar, and the main source of energy for the human body is also sugar, such as starch, maltose, glucose and so on in food.
Carbohydrates can be divided into monosaccharides, disaccharides and polysaccharides, which are gradually broken down until they are deconstructed into the monosaccharides that we can use.
Then some people may have to ask, the human body's energy storage substance is only one kind of sugar, the human body's fat and protein do not also have the function of energy storage.
If I don't eat, will my body use these two reserve energy? So let's take a look at the two important substances of fat and protein.
Protein is an important macromolecule of life, distributed in all cells of the human body, it is a polymer compound formed by the dehydration and condensation of a variety of amino acids.
It is quite functional, and when the body needs to build and repair itself, protein begins to play its role.
For example, the formation of our bones, nails, and hair all require the participation of proteins; Proteins are also involved in hormonal regulation.
For example, growth hormone, insulin; Many of the antibodies produced by the body to fight bacteria and viruses after illness are proteins; The muscles that control the movement of the body contain a large amount of myogenic protein, rhabdomyolysis.
It is because muscle protein is broken down, a large number of amino acids rush into the blood, which brings a huge burden to the kidneys, and severe cases can lead to acute kidney failure.
But in general, protein is not used to supply energy, and protein is only possible to be broken down when people's health is so poor that it is life-threatening.
It can be seen that the main role of protein is more focused on maintaining some specific functions of the human body, which is rarely used by the human body to break down to supply energy.
As we said earlier, sugar is an important energy storage substance, fat as a lipid, compared with sugar, has better energy storage properties, why say so?
Fat has a higher proportion of hydrocarbons, and the same quality of fat and sugar, in oxidative decomposition, fat can consume more oxygen and release more energy.
In addition to supplying energy, fat also protects the internal organs, reduces the pressure on the internal organs when impacted, and maintains a constant body temperature.
From the above, we can understand that fat only begins to be broken down when the sugar is almost depleted.
For example, the ambient temperature suddenly drops, or after high-intensity exercise, muscle contraction requires a lot of energy, and when the energy supply of sugar is insufficient, fat is needed to compensate.
The different living habits of each person we mentioned earlier will lead to different degrees of hunger tolerance for each person, and if someone exercises regularly, then there will be more mitochondria in his cells than those who do not exercise.
Mitochondria are the organs that supply energy to human cells, and cells absorb glucose from the blood circulation to supply mitochondria for oxidative decomposition and produce a large amount of energy.
This is how sugars are broken down into glucose, enter cells, and finally convert into energy.
More mitochondria means he has more digestive power and is more likely to be hungry than a person who does not exercise.
In addition, there are some people who burn out energy quickly due to illness, and the second part of this article will be analyzed in combination with specific diseases.
To this point, let's sort out the reasons for the panic and tremor when you are hungry, and the panic and tremor that can be associated with hunger are basically due to insufficient energy supply or nerve problems required by the corresponding muscles.
The intuitive manifestation is that the stability of the muscles will decrease. Among them, the insufficient energy supply is mainly because after the sugar is consumed, the reserve energy cannot be replenished immediately.
Neurological problems are often due to some diseases, sometimes hunger hand trembling is only one of the two, sometimes it will appear at the same time, need to be analyzed according to the condition
Second, panic and tremor after hunger are related to these three diseases
1. Hypoglycemia
After a long period of hunger, our blood sugar levels will become very low, dizzy, and all the muscles of the body need to consume a lot of energy for the proper functioning.
But the most important blood sugar can not be supplied in time, then other substances are needed to supplement, but the replenishment process takes time.
As mentioned earlier, each person's specific situation is different, for example, a person's usual blood sugar level is lower than others, skipping breakfast can easily lead to blood sugar to a lower level than the reference value (adult blood sugar level should be higher than 2.8 millimoles per liter).
The main symptoms of hypoglycemia may include muscle tremor, sweating, palpitations, etc., and patients with severe hypoglycemia symptoms should rest immediately and supplement energy through eating or oral glucose.
If you know that you are prone to hunger and hypoglycemia, you should carry some snacks that can replenish energy in time, such as chocolate, and you should avoid skipping breakfast.
Besides hunger, what else can cause low blood sugar?
Hunger is a situation of insufficient sources, so does excessive consumption also cause hypoglycemia?
There are a large number of hormones in the human blood circulation, although these hormones are very small, but their role cannot be underestimated.
For example, insulin that can lower blood sugar, some diabetic patients have insufficient insulin secretion, and clinically let patients take drugs that promote insulin secretion, but if they are used excessively, blood sugar drops sharply, and hypoglycemia may also occur.
It is necessary to know that patients with prediabetes will also tremble in fasting or hunger, sweat cold, and pale, so pay attention to the physical condition in time, do not disagree.
2. Heart problems
Atrial fibrillation is one of the most common arrhythmias in clinical practice and can lead to complications such as stroke (commonly known as stroke) and heart failure.
Heart failure caused by various causes, insufficient blood output of the heart, can reduce various functions of the body.
Severe heart failure can be life-threatening; Tachycardia is hereditary and acquired, resulting in chest tightness, shortness of breath, dizziness and other symptoms.
In summary, the palpitation and tremor caused by various heart problems are basically caused by the decline in heart function, once you find that there are related symptoms, you should immediately go to the hospital for examination.
3. Hyperthyroidism
The main types and causes of hyperthyroidism
Hyperthyroidism is what we often call hyperthyroidism, the vast majority of hyperthyroidism is Graves hyperthyroidism, which belongs to an autoimmune disease, and the common causes are family inheritance, immune response, mental overtension, etc.
Among them, family inheritance and mental stress we need not say more, the immune response caused by Graves hyperthyroidism is generally due to certain bacterial infections.
A substance called thyroid-stimulating hormone receptor antibody is produced, the name is so long, what is it for?
Then we must first know that there is a concept called hierarchical regulation in the hormonal regulation of the human body.
The body needs to control the secretion of thyroid hormone, and the thyroid gland, as an organ that secretes thyroid hormone, has a receiver used to receive signals (thyroid-stimulating hormone, TSH) from its parent (adenopituitary gland).
That is, thyroid-stimulating hormone receptors, that the adenopituitary gland naturally has its upper level (hypothalamus), and the hypothalamus sends signals (thyroid-stimulating hormone-releasing hormone, TRH).
So if you have been secreting thyroid hormones, of course not, our delicate body has long considered it, when the thyroid secretes too much, there are corresponding sensors in the hypothalamus that will receive it.
It is as if the leader goes to the grassroots level to investigate, the whole is a complete system, which can ensure the normal secretion of our hormones.
In addition to the secretion of the thyroid gland, the secretion of the human body also has cortisol and gonadal hormones.
The role of this thyroid-stimulating hormone receptor antibody is to bind to TSH receptors on thyroid cell membranes, promote the function of the thyroid gland, and lead to hyperthyroidism.
Hyperthyroidism can lead to increased digestion, energy will be consumed particularly quickly, and hunger, hand tremors and sweating will be prone to occur.
Patients with hyperthyroidism should avoid iodine-containing foods (iodized salt, kelp, etc.) in their diet, why not eat iodine?
We note that the structural formula of thyroid hormones contains iodine, and the synthesis of thyroid requires a large amount of iodine, and avoiding taking iodine can reduce the synthesis of thyroid hormones, thereby slowing down the disease.
3. In addition to the above three diseases, the causes of hand trembling and palpitation caused by hunger may also be drug poisoning, Parkinson's syndrome, cerebral atrophy and hepatic encephalitis.
If the body is unwell, you should go to the hospital in time to seek the help of a doctor, detect the disease as soon as possible, take effective measures, and avoid taking medicine blindly and indiscriminately.
