Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
As per your complain and presentation of symptoms
excessive salivation will definitely increase the urge to swallow and as you keep burping the problem is related to digestive problem causing
Hyperacidity and acid reflux.
Due to acid reflux there is acid regurgitation from stomach to mouth leading to irritation in throat and mouth causing stimulation in salivary glands and causing excessive salivation..
Nothing to worry, you can take
Proton Pump Inhibitors like
Pantoprazole or Omeprazole.
Take antacid like
Milk of magnesia half an hour before meals.
Drink plenty of water.
Take more of Probiotics like Yoghurt in your diet.
Avoid spicy and acidic foods.
Take small meals and prevent heavy and large meals.
Eat small portions of food every 2 to 3 hours.
Take a short walk after meals.
Avoid stress by doing meditation.
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
