Introduction

Generalized weakness, fatigue, loss of appetite, and excessive sleepiness may result from physiological causes, or could be due to pathological conditions such as anemia or depression, requiring treatment based on specific circumstances. Engaging in heavy physical labor can lead to excessive bodily exhaustion, resulting in symptoms such as generalized fatigue, poor appetite, and reduced mental alertness, which usually improve after adequate rest.

Generalized weakness, fatigue, loss of appetite, and excessive sleepiness may result from physiological causes, or could be due to pathological conditions such as anemia or depression. Treatment depends on the specific underlying cause. Details are as follows:

1. Physiological Causes

Engaging in heavy physical labor can lead to excessive fatigue, resulting in symptoms such as generalized weakness, poor appetite, and low energy. These symptoms typically improve after adequate rest.

2. Pathological Causes

1) Anemia

Anemia can cause ischemia in brain and muscle tissues. Cerebral ischemia leads to drowsiness and mental lethargy, while muscle ischemia results in body weakness and easy fatigability. Treatment may include iron supplements such as ferrous sulfate tablets, ferrous sulfate sustained-release tablets, or ammonium ferric citrate effervescent granules, taken under medical supervision.

2) Depression

Prolonged mental stress may lead to depression, causing symptoms such as low energy, depressed mood, eating disorders, and physical fatigue. Medications such as fluoxetine hydrochloride tablets, venlafaxine hydrochloride tablets, or sertraline hydrochloride dispersible tablets may be prescribed and taken according to medical advice.

In addition, these symptoms may also be caused by conditions such as narcolepsy, heart failure, or hypothyroidism. It is recommended that patients seek timely medical evaluation for accurate diagnosis and appropriate treatment.

Can Artemisia selengensis improve poor appetite?

Artemisia selengensis may have a certain auxiliary effect in improving loss of appetite; however, attention should be paid to cooking methods and portion control, as it cannot resolve all types of appetite issues.
