Gastrointestinal Symptoms After COVID-19: When to Seek Help - Gastroenterology and Hepatology

Stomach pain, vomiting, and diarrhea?


I was diagnosed with COVID-19 on June 28.
After experiencing fever for two days, I started having stomach pain, along with symptoms of vomiting and diarrhea.
I visited a clinic, and the doctor said it was due to taking over-the-counter medication incorrectly.
After completing my quarantine, the stomach pain and other symptoms did not improve.
I returned to the doctor, who prescribed medication for nausea and diarrhea, but my symptoms worsened instead, and even the color of my stool changed to orange.
I would like to ask if this is a post-COVID-19 complication or if there is an issue with my stomach itself.
Should I go directly to a major hospital for treatment?

If symptoms do not improve, you may visit a gastroenterology outpatient clinic for evaluation and treatment.

Understanding gastrointestinal symptoms after a COVID-19 infection can be complex, as the virus has been shown to affect multiple organ systems, including the gastrointestinal (GI) tract. Your symptoms of persistent stomach pain, vomiting, and diarrhea following your COVID-19 diagnosis raise important questions about whether these issues are related to the virus itself or if they indicate a separate gastrointestinal problem.

Firstly, it is essential to recognize that COVID-19 can lead to a variety of gastrointestinal symptoms. Studies have indicated that a significant number of patients experience GI symptoms such as nausea, vomiting, diarrhea, and abdominal pain during or after their COVID-19 infection. These symptoms can occur due to direct viral effects on the gastrointestinal lining or as a result of the body's immune response to the virus. In some cases, these symptoms may persist even after the acute phase of the infection has resolved, leading to what is often referred to as "long COVID" or post-acute sequelae of SARS-CoV-2 infection (PASC).

In your case, the onset of gastrointestinal symptoms following the resolution of fever suggests that these symptoms could indeed be related to your COVID-19 infection. However, the fact that your symptoms worsened after taking anti-nausea and anti-diarrheal medications raises concerns about the underlying cause of your gastrointestinal distress. The change in stool color to orange could indicate several things, including the presence of bile, which can occur when the intestines are not processing food normally, or it could be related to the medications you are taking or the foods you are consuming.

Given that your symptoms have not improved and have even worsened, it is advisable to seek further medical evaluation. While your initial visit to a clinic provided some insight, the persistence and worsening of your symptoms warrant a more thorough investigation. A visit to a gastroenterologist or a larger hospital may be necessary to rule out any serious underlying conditions, such as infections, inflammatory bowel disease, or complications related to your COVID-19 infection.

In addition to seeking medical help, there are several steps you can take to manage your symptoms in the meantime:
1. Hydration: Ensure you are staying well-hydrated, especially if you are experiencing diarrhea and vomiting. Oral rehydration solutions can be beneficial.

2. Diet: Stick to a bland diet that is easy on your stomach. Foods like bananas, rice, applesauce, and toast (the BRAT diet) can help. Avoid fatty, spicy, or heavy foods that may exacerbate your symptoms.

3. Monitor Symptoms: Keep a detailed record of your symptoms, including their frequency, duration, and any changes in your stool. This information will be helpful for your healthcare provider.

4. Avoid Self-Medication: Be cautious with over-the-counter medications, as they can sometimes mask symptoms or lead to complications. Always consult with a healthcare professional before taking new medications.

5. Follow-Up: If you experience new symptoms such as high fever, severe abdominal pain, blood in your stool, or signs of dehydration, seek immediate medical attention.

In conclusion, while your gastrointestinal symptoms could be related to your recent COVID-19 infection, the persistence and worsening of these symptoms necessitate further evaluation by a healthcare professional. A gastroenterologist can provide a comprehensive assessment and appropriate management to address your symptoms effectively.
