I've been taking stomach medicine for several days, but I still feel nauseous.

In general, still feeling nauseous after taking stomach medication for several days may be caused by factors such as drug side effects, food poisoning, or gastritis. A detailed analysis is as follows:

1. Drug Side Effects

Certain stomach medications may cause gastrointestinal discomfort, including antibiotics, antacids, and other drugs. In addition, some over-the-counter medications, such as aspirin tablets and ibuprofen tablets, can also lead to these symptoms. If such symptoms occur, it is important to consult a doctor promptly to understand the potential side effects and precautions associated with the medication.

2. Food Poisoning

Food poisoning can also cause nausea. It is an illness resulting from consuming contaminated food or drinking contaminated water. Symptoms of food poisoning include nausea, vomiting, diarrhea, and others. If food poisoning is suspected, prompt medical attention is recommended.

3. Gastritis

Gastritis caused by bacterial infection can also lead to symptoms such as nausea and vomiting during an episode. Additionally, it may cause abdominal pain, diarrhea, constipation, and other symptoms.

Besides the above common causes, nausea might also result from conditions such as gastric ulcers, cholecystitis, or gallstones. It is advisable to seek timely medical evaluation at a hospital to determine the exact cause and receive targeted treatment. In daily life, maintain healthy habits and avoid consuming spicy or irritating foods, which could otherwise hinder recovery.
