I feel weak all over when I'm hungry

It is normal to feel weak when you are hungry, but feeling weak all over when you are hungry may also be a sign of health problems. There are many reasons for this. In fact, if you pay attention, you can tell the difference between normal hunger and abnormal hunger. If it is caused by a disease, it should be taken seriously and the situation must be clarified as soon as possible. So, why do you feel weak all over when you are hungry? Let’s take a look below.

The energy for human physiological activities comes directly from blood sugar, which comes from nutrients obtained from food by digestive organs such as the small intestine. The reason why people are hungry is that the blood sugar concentration decreases, which leads to normal physiological reactions. It is time to replenish food (that is, eat). If you do not replenish food immediately at this time, after a while, the physiological reaction will prompt the decomposition of glycogen (derived from the decomposition of cellular fat, the process is completed by bile). At this time, people will feel that they have passed the hunger mark, but they are no longer hungry.

The most direct reason for being hungry is low blood sugar concentration, but there may be many reasons.

The first one : there is something wrong with the blood. Some people's blood sugar concentration is always lower than normal due to characteristic (genetic) reasons. As a result, they are always hungry and do not feel comfortable even if they eat until they are full. They are weaker and have weak immunity. They may get sick frequently and have no energy. (Go for a blood test)

The second type is poor digestive tract function. If the digestive organs such as the small intestine and stomach cannot work properly, food cannot be completely converted into the nutrients needed by the body, resulting in low blood sugar concentrations. It is easy to get hungry and feel hungry shortly after eating. (Go for a gastrointestinal examination, including the mouth, esophagus, gallbladder, etc.)

The third type: It may also be caused by excessive secretion of thyroid hormones, which will cause the patient to be very thin and have a bad temper (commonly known as hyperthyroidism, it is recommended to go to the hospital to test the thyroid gland).

The fourth type: If you cannot stand being hungry, it is "annoying hunger", which may be caused by abnormal liver function. When the blood sugar concentration decreases, the liver cannot make the correct physiological response to break down glycogen to maintain normal activity energy, so it continues to consume the little glycogen in the blood, causing increasingly severe physiological reactions. (Hungry, annoyingly hungry). [It is recommended to check the liver and gallbladder function. The gallbladder plays a very important role. Even if the liver function is normal, if the gallbladder function is abnormal, fat cannot be converted into energy substances normally, which will lead to the same consequences, but people will gain weight and cannot eat greasy food.]

The fifth type: It may be a kidney problem. Nutrients must be filtered by the kidneys. If there is a problem with the kidneys, nutrients cannot enter the blood circulation normally. This causes the body to be in a state of nutritional deficiency, which manifests itself as hunger. (It is recommended to check kidney function, renal tubules and filters, which may lead to diabetes. The person will be thinner, have bad skin, rashes, etc., and the urine color is abnormal)

The sixth type: It may be a combination of the above reasons. Humans are very sophisticated and advanced instruments. Often when the damage is relatively minor, they can rely on their own physiological reactions to adjust and give prompts. So when you feel very uncomfortable, your body functions have already declined to a considerable extent, so sometimes the causes of a disease are often a mixture of several factors.

Simple self-test method:

1: Evaluate your own obesity level. If you are obese, you are probably in the fourth or sixth category.

2: Evaluate your own level of physical excitement. If you are excited, it is probably level 3 or 6.

3: Evaluate your own athletic ability. If you can do very intense exercise and sweat profusely continuously, then you can rule out liver and gallbladder problems.

4: Evaluate your own immune system. If your immunity is not strong, you will easily get sick, most likely the first or sixth type.

5. Evaluate the color of urine. If it is yellow and thick, it is most likely the fifth or sixth type.

6: Excluding other possibilities, the second or sixth one is most likely the answer.

If the symptoms are not very obvious or severe, most of the above symptoms can be ruled out and it may be caused by mild indigestion.

If the person is doing heavy physical labor, this is a normal reaction.
