[20F] Experiencing postprandial dizziness with tunnel vision

What might be happening

Based on the symptoms you've described, here are some possible explanations:

1. Postprandial Hypotension: This condition occurs when blood pressure drops significantly after eating. It can cause dizziness, lightheadedness, and even fainting. It happens because blood flow increases to the digestive tract, which can reduce blood flow to other parts of the body. Monitoring your blood pressure during these episodes can help confirm this.

2. Reactive Hypoglycemia: This is a condition where blood sugar levels drop after eating, leading to symptoms like dizziness, shakiness, and sweating. It can occur if your body produces too much insulin in response to a meal, especially one high in carbohydrates.

3. Vasovagal Response: This is a reflex that can cause a sudden drop in heart rate and blood pressure, leading to dizziness and fainting. It can be triggered by eating in some individuals.

Typical treatments or testing for these conditions might include monitoring your blood pressure and blood sugar levels, dietary adjustments, and possibly further evaluation by a healthcare provider to rule out other causes.

What you can do

1. Dietary Adjustments: Since eating smaller, more frequent meals seems to help, continue with this approach. Try to include a balance of protein, healthy fats, and complex carbohydrates to maintain stable blood sugar levels.

2. Stay Hydrated: Ensure you are drinking enough water throughout the day, as dehydration can exacerbate dizziness.

3. Monitor Symptoms: Keep a journal of your symptoms, including what you eat and when the dizziness occurs. This can help identify any patterns or triggers. You can use MDandMe to track your symptoms and share this information with your healthcare provider.

4. Consult a Healthcare Provider: It's important to discuss these symptoms with a healthcare professional who can provide a formal diagnosis and recommend appropriate tests or treatments.

What you should look out for

• Seek Medical Attention: If your symptoms worsen, become more frequent, or if you experience additional symptoms like chest pain, severe headache, or loss of consciousness, seek medical attention promptly.

• Monitor for Other Symptoms: Pay attention to any new symptoms that may arise, such as changes in vision, heart palpitations, or significant changes in weight, and report these to your healthcare provider.

Remember, while this information can be helpful, it's important to consult with a healthcare professional for a comprehensive evaluation and personalized advice.
