Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you are suffering from
Gastro esophageal reflux disease also commonly known as Acid reflux..
It occurs due to weakening of band of muscles at the lower end of esophagus also known as Lower esophageal sphincter..
As during the lying position there is easy regurgitation of the acid and so there is more reflux of acid from stomach to throat and mouth in lying position..
I would suggest you to
consult a Gastroenterologist and get evaluated and a thorough clinical evaluation and investigations like Upper G. I Endoscopy can help in diagnosis and he can advise you to take
Proton pump inhibitor like
Pantoprazole or Omeprazole, antacid like
Milk of Magnesia, H2 blockers like Ranitidine..
Drink plenty of water and take Probiotics like Yoghurt in diet..
You should loose weight if obese..
You can avoid spicy and chilled foods..
Take short frequent meals ever 2 hours..
Take walk after meals..
Take your dinner atleast 2 hours before sleeping..
Sleep with head slightly raised as compared to feet to prevent reflux..
Hope this information helps..
Thanks and regards.
