Why do I feel weak and limp all over my body?

Feeling weak and lethargic throughout the body may be caused by factors such as sleep deprivation, hypoglycemia, iron deficiency anemia, insufficient cerebral blood supply, or hypothyroidism. It is recommended to seek medical attention promptly and follow medical advice for improvement through general treatments, medications, and other methods. Specific analyses are as follows:

1. Sleep Deprivation

If one frequently stays up late over a long period, it may lead to inadequate sleep and poor physical rest, resulting in symptoms such as fatigue and dizziness. It's important to maintain healthy lifestyle habits, avoid staying up late, and ensure sufficient sleep.

2. Hypoglycemia

This may be related to improper diet or excessive physical activity, leading to low plasma glucose levels and causing the aforementioned symptoms. Immediately consuming foods high in sugar, such as candies or cakes, can help relieve discomfort.

3. Iron Deficiency Anemia

This may result from insufficient iron intake or excessive blood loss, causing symptoms including fatigue, pale complexion, and dizziness. Patients may take medications such as ferrous gluconate syrup, ferrous sulfate syrup, or ferrous fumarate granules under medical guidance to improve their condition.

4. Insufficient Cerebral Blood Supply

This may be associated with irregular lifestyles or poor posture, potentially causing cerebrovascular circulation disorders and symptoms such as dizziness and bodily weakness. Under a doctor’s supervision, patients may use medications such as enteric-coated aspirin tablets, nimodipine tablets, or warfarin sodium tablets for treatment.

5. Hypothyroidism

This may be caused by improper diet or autoimmune damage, leading to reduced secretion of thyroid hormones and symptoms such as physical fatigue and memory decline. Patients may take medications such as levothyroxine sodium tablets, thyroid tablets, or Yikang capsules as directed by a physician to improve symptoms.

In daily life, it's important to get adequate rest, ensure sufficient sleep, avoid staying up late, and engage appropriately in outdoor activities such as walking or calisthenics, which can aid in recovery.
