Loss of Appetite and Nausea: Gastrointestinal Issues

Poor appetite and vomiting after meals?

Last night, I had an upset stomach and no appetite.
I ate a little for dinner but kept running to the bathroom feeling nauseous.
I couldn't vomit much at first, but eventually, I threw up everything I had eaten for dinner.
Later, I went to see a doctor who said I have mild gastritis.
Today, my appetite is still poor, and my stomach still feels uncomfortable.
For lunch and dinner, I only ate a little, and afterward, I still felt nauseous.
I ended up vomiting white, somewhat bitter substance, which I believe is the medication I took.
What should I do? My medication is to be taken after each meal and before bedtime.
My stomach feels uncomfortable but not painful.

More Info

Loss of appetite and nausea can be distressing symptoms that often indicate underlying gastrointestinal issues. Based on your description, it seems that you are experiencing a combination of gastritis (inflammation of the stomach lining) and possibly some form of gastrointestinal upset, which could be related to your recent meals or medications.

When the stomach is inflamed, it can lead to symptoms such as nausea, vomiting, and a decreased appetite. The fact that you are experiencing a bitter taste when vomiting suggests that bile may be present, which can occur if the stomach is empty or if there is a reflux of bile from the duodenum into the stomach. This can happen when the stomach is irritated or not functioning properly.

Here are some steps you can take to manage your symptoms:
1. Dietary Modifications: Stick to a bland diet to avoid further irritation of your stomach. Foods such as bananas, rice, applesauce, and toast (often referred to as the BRAT diet) can be gentle on the stomach. Avoid spicy, fatty, or acidic foods, as well as caffeine and alcohol, which can exacerbate inflammation.

2. Hydration: Ensure you stay hydrated, especially if you are vomiting. Sip on clear fluids like water, broth, or electrolyte solutions. Avoid drinking large amounts at once, as this may trigger further nausea.

3. Medication Management: Since you mentioned that you are on medication, it’s crucial to discuss with your doctor whether these medications could be contributing to your nausea. If you are unable to keep your medications down, inform your healthcare provider. They may need to adjust your treatment plan or prescribe anti-nausea medication.

4. Rest: Give your body time to recover. Stress and fatigue can worsen gastrointestinal symptoms, so ensure you are getting adequate rest.

5. Monitor Symptoms: Keep track of your symptoms. If your nausea persists, or if you experience severe abdominal pain, fever, or blood in your vomit or stool, seek medical attention promptly. These could be signs of a more serious condition that requires immediate intervention.

6. Follow-Up: Since you have already seen a doctor, it’s important to follow up if your symptoms do not improve within a few days. Your doctor may recommend further tests, such as an endoscopy, to assess the condition of your stomach and rule out any serious issues.

In conclusion, while loss of appetite and nausea can often be attributed to gastritis or other gastrointestinal disturbances, it is essential to monitor your symptoms closely and maintain open communication with your healthcare provider. By making dietary adjustments, staying hydrated, and managing your medications, you can help alleviate your symptoms. If your condition does not improve, further evaluation may be necessary to determine the underlying cause and appropriate treatment.
