Often feel listless and weak

Most people think that general weakness is a symptom of excessive fatigue, but this is indeed the case for most people in life. Gradually, everyone will get used to it and feel that this situation does not need to be paid too much attention. However, don’t forget that in addition to feeling listless and weak due to excessive fatigue, lack of sleep, colds, diabetes, etc. can all cause patients to experience such symptoms.

Fatigue: Fatigue among people who do physical or mental work is a normal physiological phenomenon, but feeling tired after just a little work is something that needs to be taken seriously.

Low blood potassium: People who frequently vomit and have diarrhea and use large amounts of diuretics may experience general weakness due to low blood potassium; however, patients with high blood potassium may also feel weak, so blood tests are needed to differentiate.

Lack of sleep: It can make people feel tired, but people with neurasthenia will also feel weak if they take sleeping pills for a long time. Other drugs that cause fatigue include antihistamines such as diphenhydramine.

Alcoholism: People who are addicted to drinking often feel tired; hungry people also feel weak due to lack of protein and potassium; fatigue and weakness are sometimes prodromal symptoms of vitamin B1 deficiency, and alcoholics are prone to this disease.

Colds and various infectious diseases: Patients with these diseases almost always experience fatigue and weakness. Heart failure patients eat less and take in less magnesium, so the ATP that provides energy cannot be activated, resulting in fatigue.

Diabetes: Diabetes is the most common disease that causes fatigue. Due to abnormal glucose metabolism, reduced high-energy phosphate bonds, negative nitrogen balance, water loss and electrolyte imbalance, patients are prone to fatigue, weakness, thirst, weight loss, polyphagia and polyuria.

Anemia: It also often causes fatigue. Severe cases include chronic anemia, sudden onset iron deficiency anemia, acute hemorrhagic anemia, acute hemolytic anemia, etc. These patients all experience fatigue.

Chronic nephritis: Patients often feel tired and weak, and because they need to eat a low-salt or salt-free diet for a long time, they are prone to potassium deficiency. Therefore, fatigue, insomnia, and low back pain are often their main complaints when they seek medical treatment.

Endocrine diseases: Many endocrine diseases present with symptoms of fatigue. Fatigue is the first symptom of patients with hypothyroidism and is also a common symptom in patients with hyperthyroidism.

Sheehan's syndrome: Sheehan's syndrome is caused by shock due to postpartum hemorrhage. The main symptoms are fatigue, amenorrhea, and weight loss. This is due to hypopituitarism. Patients with acromegaly caused by hyperpituitarism also often feel fatigue and weakness in the limbs.

Myasthenia gravis: The most obvious fatigue and weakness are seen in myasthenia gravis patients. Due to the patient's neuromuscular conduction disorder, their skeletal muscles are extremely easy to fatigue. After a little activity, they quickly become weak. Continuous and rapid movements are more likely to cause fatigue. The feeling of fatigue is often lighter in the morning and heavier in the evening. Fatigue can be relieved after supplementing with potassium chloride.

Leukemia: Patients often feel weak because they also suffer from anemia. In addition to leukemia, many malignant tumors often manifest as fatigue symptoms in the early stages, but are also accompanied by other common symptoms of the tumor. For example, lung cancer often has symptoms such as cough, hemoptysis, chest pain, etc.
