Hello.
Thank you for asking at HCM.
I would think you have
allergic rhinitis.
As your question is about diet, I would suggest you following:
1. Avoid cold foods (cold drinks, cold water, cold sweets, ice creams, etc)
2. Avoid too hot and too spicy foods.
3. Avoid heavy meals at evening/night.
4. Take nutritious balanced diet involving sufficient amount of whole grains, green vegetables, fruits, nuts & legumes & dairy - this is for overall health and a good immune system.
5. Unless you are allergic/intolerant specifically to some foods, you can take all foods.
As an allergist, I would like to say that
sneezing every morning is usually due to house dust
mite allergy. I would suggest you to take
levocetirizine and
montelukast daily.
Also, daily nasal wash with nasal saline spray 3-4 times a day will help. Please ensure good ventilation and sunlight into the bedroom. Please try to avoid dust-smoke-air pollutants when possible.
Hope this will be helpful to you.
Wish you best of the health.
Regards.
