Whether gastroenteritis is contagious depends on the cause of the inflammation. For example, if a person develops abdominal pain and diarrhea from getting cold, this type of gastroenteritis, caused by chilling, is not contagious, so it will not spread from person to person. However, if the gastroenteritis is caused by bacterial dysentery (commonly known as bacillary dysentery), it can be spread through food. Therefore, whether gastroenteritis is contagious depends on the infecting pathogen and the cause; it cannot be generalized.

Does acute gastroenteritis cause stomach pain?

Acute gastroenteritis, due to inflammation of the gastrointestinal tract, can cause gastric colic. Clinically, it may manifest as upper abdominal pain, nausea, vomiting, and diarrhea. It often occurs in the summer and is directly related to improper diet. It can cause not only stomach pain but also electrolyte imbalance, intestinal perforation, and sepsis. Active use of medications should be undertaken for treatment, with attention to prevent dehydration. During the treatment period, eat a light diet, avoid spicy food, rest well, and keep the abdominal area warm.

Does acute gastroenteritis hurt?

When suffering from acute gastroenteritis, the inflammation can cause irregular and accelerated intestinal peristalsis, which may lead to intestinal spasms and colic. In such cases, the first step should be proactive anti-inflammatory symptomatic treatment. Then, applying a heat pack on the stomach and drinking more hot water can help alleviate the symptoms. If the pain is severe, and the patient is sweating profusely, looks pale, and has cold hands and feet, going to the hospital for an intramuscular injection of Scopolamine Butylbromide can relieve smooth muscle spasms and relax the muscles, thereby easing the pain. Therefore, it is important to pay attention to dietary hygiene. It is crucial to thoroughly heat or cook food taken out from the refrigerator before eating, as prevention is more important than treatment.

Symptoms of gastroenteritis and cold

Gastroenteritis and the common cold generally manifest as two types of symptoms in clinical settings. The first type includes symptoms caused by upper respiratory tract infections. The second type involves gastrointestinal symptoms. Common symptoms of upper gastrointestinal tract infections include fever, fatigue, dry cough, coughing, sore throat, runny nose, and itchy throat, etc., typically lasting about a week. These symptoms are usually nonspecific and similar to those of a typical upper respiratory tract infection. The second type of symptoms generally involves gastrointestinal issues, presenting as abdominal discomfort, bloating, leg pain, and abnormal stool. Clinically, abnormal stools are often looser and more frequent, but typically do not involve bloody stools. These symptoms are generally not severe and can be observed.

How to alleviate acute gastroenteritis

For acute gastroenteritis, the first step is to provide general treatment, which is to have the patient rest in bed as much as possible. For mild cases, oral rehydration solutions can be used to replenish lost fluids. If the patient has persistent vomiting or noticeable dehydration, they need to replenish with glucose-salt water or other relevant electrolytes. Patients should try to eat a light diet, consisting of semi-liquid foods, to prevent dehydration. Secondly, symptomatic treatment should be administered if necessary, including injections of antiemetic and antispasmodic medications, as well as antidiarrheal drugs. Thirdly, antimicrobial treatment, which is mainly targeted at infectious diarrhea, should involve the appropriate use of targeted antibiotics, but it is important to prevent their misuse.

Can you smoke with gastroenteritis?

If suffering from gastroenteritis, the main clinical symptoms usually include abdominal pain, diarrhea, nausea, vomiting, or fever. If these symptoms occur, it is best to test the stool and blood to determine whether the infection is bacterial or viral, and then treat accordingly. It is not recommended for patients with gastroenteritis to smoke, as smoking primarily harms the lungs, easily causing chronic bronchitis, asthma, or even allergies. Furthermore, smoking can affect the blood concentration of medications, thus during the treatment of gastroenteritis with oral medications or intravenous infusions, smoking can affect the efficacy of the treatment. Therefore, patients with gastroenteritis should not smoke.
