• Avoid acid or heartburn-triggering foods or drinks like onions, peppermint, chocolate, caffeinated beverages, citrus fruits or juices, tomatoes and high-fat and spicy foods.

• Before going to sleep, raise your bedhead, so your head and chest are higher than your feet. Do not use piles of pillows; one raised block is fine. This will not allow the stomach acid to backflow through your food pipe.

• Avoid taking alcohol and smoking cigarettes. Alcohol can raise the production of stomach acid leading to heartburn and acid reflux. On the other hand, nicotine smoking damages the valve (sphincter), preventing stomach acid backflow into the food pipe.

• Include high fibre-containing foods, berries, cherries, leafy green veggies (kale, spinach) and black peppers in your meal.

• Fermented dairy products like miso, sauerkraut, and kimchi contain probiotics which help prevent excess stomach acid production. Cranberry juice can be beneficial for peptic ulcers and H Pyroli infections.

• Avoid regular sitting continuously, as it can increase stomach acid production. Take a break of 5 minutes in 1 hour by brisk walking or stretching.

The stomach is usually protected from acid by a mucous layer. In some cases, excess acid production erodes the mucous layer, which leads to complications like acidity. Due to this, acid frequently flows back into the food pipe (oesophagus). This backflow (acid reflux) irritates the food pipe and causes heartburn. Symptoms include heartburn, sour or bitter taste in the mouth, and difficulty swallowing. Indigestion is the feeling of fullness. It occurs due to slow gastric emptying. Symptoms include stomach pain, bloating, heartburn, nausea and vomiting.

Gastroesophageal reflux disease (GERD): The stomach is usually protected from acid by a mucous layer. In some cases, the mucous layer gets irritated or eroded due to excess acid production, which leads to complications like GERD, hyperacidity, peptic ulcers, and heartburn. Gastroesophageal reflux disease (GERD) occurs when stomach acid frequently flows back into the food pipe (oesophagus). This backflow (acid reflux) irritates the food pipe and causes heartburn. Symptoms include heartburn, sour or bitter taste in the mouth, and difficulty swallowing.

Peptic ulcers are sores that develop on the stomach and intestine lining due to erosion of the stomach's protective lining. Symptoms include nausea, appetite changes, bloody or dark stools, unexplained weight loss, vomiting, and indigestion.

Zollinger-Ellison syndrome: It is characterized by the formation of tumours in the upper part of the small intestine, which leads to excess acid production. Symptoms include bloating, burping, weight loss, loss of appetite, nausea, and vomiting.
