Why do I always feel sleepy and weak all over?

Frequent drowsiness and generalized weakness may be caused by physiological factors or pathological conditions such as neurasthenia, depression, etc. The specific analysis is as follows:

I. Physiological Causes

This may result from chronic sleep deprivation due to long-term late-night habits. Prolonged lack of sleep can lead to decreased organ function and cause the aforementioned symptoms. In such cases, no special treatment is required—simply adjusting the sleep schedule can improve the condition. It is recommended to maintain sufficient sleep duration.

II. Pathological Causes

1. Neurasthenia

Long-term mental stress or emotional suppression may lead to neurasthenia, resulting in poor mental state, reduced memory, difficulty concentrating, and excessive sleepiness. Treatment may include medications such as vitamin B12 tablets or oryzanol tablets, taken under medical guidance.

2. Depression

Psychological issues leading to depression can cause slowed reactions, loss of interest in daily activities, and a tendency to use sleep as an escape from difficulties and life challenges. Treatment may involve antidepressants such as paroxetine hydrochloride tablets or venlafaxine hydrochloride sustained-release tablets, as prescribed by a doctor, along with efforts to relax and improve mood.

In addition, conditions such as hypothyroidism, diabetes, and renal failure may also cause similar symptoms. Therefore, it's important to identify the underlying cause and receive targeted treatment. If symptoms persist without improvement, prompt medical consultation is advised.
