Suspected blood-tinged vomiting associated with COVID-19?


Hello, doctor.
I was recently diagnosed with COVID-19, and my prominent symptom is severe vomiting.
I not only vomit after eating but also wake up in the middle of the night to vomit.
After multiple episodes of vomiting, I have started to notice dark brown material, possibly with blood streaks, and it seems to be increasing in amount.
I would like to know if this is normal and how I can improve this situation.
Additionally, I would like to ask what foods I can eat under these circumstances.
Thank you, doctor.

Experiencing vomiting, especially with blood-tinged symptoms, can be concerning, particularly in the context of a recent COVID-19 diagnosis. It’s important to understand the potential causes and implications of these symptoms, as well as how to manage them effectively.

Firstly, vomiting is a common symptom associated with COVID-19, although it is not as frequently reported as respiratory symptoms. The presence of deep brown or blood-tinged vomit can indicate several underlying issues. The brown color may suggest that the vomit contains old blood, which could arise from irritation or damage to the gastrointestinal tract, possibly due to excessive vomiting or a more serious condition such as a bleeding ulcer or esophageal tear.

In your case, the fact that you are experiencing vomiting multiple times, even during sleep, is concerning. This could lead to dehydration, electrolyte imbalances, and further gastrointestinal irritation. The presence of blood or brownish vomit warrants immediate medical attention, as it may indicate a more serious condition that requires intervention.

Here are some steps you can take to manage your symptoms and improve your condition:
1. Stay Hydrated: It’s crucial to maintain hydration, especially if you are vomiting frequently. Try sipping clear fluids such as water, broth, or electrolyte solutions. Avoid caffeinated or sugary drinks, as they may worsen nausea.

2. Dietary Adjustments: When you feel ready to eat, start with bland foods that are easy on the stomach. Options include bananas, rice, applesauce, and toast (often referred to as the BRAT diet). Gradually reintroduce other foods as tolerated, avoiding spicy, fatty, or acidic foods that may irritate your stomach.

3. Rest: Ensure you are getting adequate rest. Your body needs energy to fight off the virus, and rest can help reduce the frequency of vomiting.

4. Monitor Symptoms: Keep a close eye on your symptoms. If the vomiting persists, or if you notice an increase in the amount of blood or brown material in your vomit, seek medical attention immediately. It’s essential to rule out any serious complications.

5. Consult a Healthcare Provider: Given the severity of your symptoms, it is advisable to consult with a healthcare provider. They may recommend further evaluation, such as imaging studies or endoscopy, to determine the cause of the bleeding and to assess the condition of your gastrointestinal tract.

6. Medications: Your doctor may prescribe anti-nausea medications to help control vomiting. Do not take any over-the-counter medications without consulting your healthcare provider, as some may not be appropriate given your symptoms.

In conclusion, while vomiting can occur with COVID-19, the presence of blood-tinged vomit is not normal and should be evaluated by a healthcare professional. It’s essential to take these symptoms seriously and seek medical advice to ensure proper management and to rule out any serious complications. Remember to prioritize hydration and start with bland foods as you recover. Your health and safety are paramount, so do not hesitate to reach out for help if needed.
