What causes yellowish complexion and general weakness?

There are many possible causes for yellowish complexion and general weakness, including anemia, cholecystitis, viral hepatitis, cirrhosis, hyperthyroidism, and other conditions.

1. Anemia

If a patient has anemia, a deficiency of red blood cells or hemoglobin in the body leads to insufficient oxygen supply, leaving organs in a state of hypoxia. This often results in symptoms such as pale-yellow skin and physical fatigue, possibly accompanied by dizziness. Under medical guidance, medications such as folic acid tablets, ferrous fumarate tablets, or iron dextran tablets may be used to promote hemoglobin synthesis.

2. Cholecystitis

Bacterial infection causing cholecystitis may lead to abdominal pain, vomiting, and nausea. As the condition progresses, jaundice may develop, resulting in yellowish skin and bodily fatigue. Under a doctor's direction, medications such as cefuroxime axetil tablets, clindamycin hydrochloride capsules, or amoxicillin capsules can be used to interfere with bacterial cell wall synthesis.

3. Viral Hepatitis

When liver damage occurs, bilirubin metabolism and excretion may be impaired, leading to elevated bilirubin levels in the blood. This commonly causes yellowing of the skin and sclera, possibly accompanied by nausea, vomiting, and generalized weakness. Under medical advice, antiviral medications such as lamivudine tablets, adefovir dipivoxil capsules, or entecavir maleate tablets may be prescribed to suppress viral replication.

4. Cirrhosis

In patients with cirrhosis, liver damage leads to reduced liver function, which in turn impairs nerve and muscle function. Excessive lactic acid accumulation in muscles can cause fatigue. Additionally, impaired liver function affects metabolism, digestion, and absorption, often resulting in a yellowish complexion, possibly accompanied by bloating, and enlargement of the liver or spleen. As directed by a physician, medications such as polyene phosphatidylcholine injection or reduced glutathione injection may be used to protect liver cell membranes.

5. Hyperthyroidism

Excessive secretion of thyroid hormones increases the body's metabolic rate, which may lead to skin pigmentation and a yellowish complexion. Symptoms may include excessive sweating and palpitations. Under medical supervision, medications such as propylthiouracil tablets, methimazole tablets, or carbimazole tablets can be used to inhibit thyroid hormone production.

It is recommended to seek timely medical evaluation, complete necessary diagnostic tests, and receive targeted treatment under a doctor’s guidance. Regular follow-up visits should be conducted during treatment to monitor disease progression.
