Acute gastritis is one of the common upper gastrointestinal diseases. The condition tends to be severe and more serious than typical gastritis, usually presenting with symptoms such as sudden onset, abdominal pain, bloating, nausea, acid reflux, and vomiting. The primary causes may include exposure to cold or food irritants, such as raw, spicy foods, or alcohol. Additionally, other factors can also lead to acute gastritis or acute gastric mucosal lesions, such as the use of non-steroidal anti-inflammatory drugs like aspirin, or corticosteroid medications such as dexamethasone or prednisone. (Specific medication use should be under the guidance of a doctor.)

Does acute gastritis cause diarrhea?

If symptoms such as abdominal pain, nausea, and vomiting occur acutely, it may be considered acute gastritis. However, if abdominal pain is accompanied by diarrhea, this condition should be considered gastroenteritis. Thus, acute gastritis generally does not cause diarrhea, whereas acute gastroenteritis can cause symptoms beyond those of the stomach, including diarrhea. Therefore, the difference between acute gastroenteritis and acute gastritis lies in the intestinal issues of the digestive tract. For the treatment of acute gastritis, medications for gastritis can be used to alleviate symptoms. Both are diseases of the digestive system, and proper examination and treatment can be sought in the gastroenterology department. (Please use medication under the guidance of a professional physician, do not self-medicate)

What should I do about acute gastritis and abdominal pain?

The abdominal pain due to acute gastritis is considered to be caused by acute gastroenteritis. The inflammation irritates the gastrointestinal mucosa, leading to muscle spasms that cause pain. It is appropriate to use antispasmodic and analgesic medications, as well as drugs that protect the gastric mucosa and inhibit gastric acid secretion. During this period, it is important to rest more and avoid physical labor as much as possible. Also, pay attention to dietary adjustments, eat soft, easily digestible foods, and avoid spicy, greasy, and irritating foods. After recovery, it is advisable to engage in appropriate outdoor exercises to regulate physical and mental health.

How many days does acute gastritis need IV fluids?

Acute gastritis, compared to chronic gastritis, has a shorter course and more severe symptoms. If the condition is not very severe, it can also be treated by taking oral medication. For example, oral proton pump inhibitors, gastrointestinal motility drugs, and mucosal protective agents, etc. If the symptoms are more severe, such as severe vomiting, intravenous fluid therapy can be administered to achieve treatment goals. The effects of intravenous fluid therapy are basically similar to those of oral medications. If the inflammation is apparent, antibiotics can be appropriately used. As for the duration of medication, generally three to five days are sufficient. If these acute gastric mucosal lesions occur, the symptoms are relatively more severe, and there may be bleeding. In such cases, the duration of intravenous fluid therapy can be appropriately extended, generally not exceeding one week.

What are the symptoms of acute gastritis?

Acute gastritis is mostly caused by unhygienic dietary habits and is more common in summer. The symptoms mainly involve gastrointestinal irritation, such as nausea, vomiting, fever, and loss of appetite. Active pharmacological treatment should be given for acute gastroenteritis. Commonly used medications include those that suppress gastric acid secretion, protect the gastric mucosa, and antibiotics. During treatment, it is advisable to eat small, frequent meals consisting primarily of soft, easily digestible foods, and to avoid cold, spicy, or irritating foods. (Please take medication under the guidance of a doctor.)

What to do if acute gastritis flares up?

Active medication is required for the recurrence of acute gastritis. The current treatment principles involve the use of medications that suppress gastric acid secretion and protect the gastric mucosa. Medications that suppress gastric acid secretion mainly include proton pump inhibitors and H2 receptor antagonists. Additionally, it is important to check for Helicobacter pylori infection. If this bacterium is present, one can choose triple therapy to eradicate it or opt for traditional Chinese medicines, which are effective in regulating the spleen and stomach. For those with obvious stomach pain, antispasmodic analgesics should be used. Regular care is also particularly important, including consuming soft, easily digestible foods and avoiding spicy, stimulating, and greasy foods, especially strong tea, coffee, and alcoholic beverages.
