Description of Acidity

Definition of Acidity
Acidity is the state of having excess acid in the stomach. Acid (gastric acid) is produced in the stomach to help in the digestion process, primarily in the breakdown of proteins. The acid in the stomach may increase due to lifestyle issues, some foods, medicines, or stress.
Causes and Risk Factors of Acidity
Eating habits that may cause acidity include:
1. Skipping meals or not eating at regular times
2. Overeating
3. Eating just before sleeping
Some foods when consumed in excess can cause acidity. These include:
1. Tea and coffee
2. Soft drinks and soda
3. Spicy foods
4. Acidic foods such as lemon and orange
5. Foods rich in fat content, especially fried foods and junk foods such as burgers, donuts, and pizzas

Acidity can also occur as a side-effect of some medicines, such as:
1. Nonsteroidal anti-inflammatory drugs (NSAIDS) such as ibuprofen and aspirin
2. High blood pressure medicines such as nifedipine and verapamil
3. Diazepam that is used to treat anxiety
4. Iron and potassium supplements
5. Tricyclic antidepressants such as imipramine or amitriptyline
6. Antibiotics such as tetracycline
7. Bisphosphonates such as alendronate, ibandronate, and risedronate that are used to cure bone diseases and strengthen the bones.

4. Nausea
5. Vomiting
6. Excessive belching or burping
7. Sour taste in mouth
Sometimes, acidity may also cause pain in the chest or upper abdomen.
Diagnosis of acidity will include a history of symptoms and tests such as: 
1. Esophageal pH monitoring to the amount of acid in the esophagus
2. Endoscopy of the esophagus and stomach
3. Biopsy of the gastric tissue
Treatments of Acidity
Acidity can be treated with medicines such as:
1. H2 receptor blockers that lower the amount of acid produced in the stomach. Examples include ranitidine, nizatidine, and cimetidine
2. Aluminum and magnesium antacids such as Gelusil and polycrol
3. Proton-pump inhibitors that block acid production, examples include omeprazole and esomeprazole
Home remedies for acidity
For immediate relief from acidity, consume the following:
1. Eat a whole banana.
2. Drink a glass of cold milk or buttermilk.
3. Drink coconut water.
4. Slowly chew half a spoon of aniseed (saunf).

Frequently Asked Questions about Acidity

Yes, acidity may occur in infants because there is immature gastrointestinal tract in infants. There is poor coordination of muscles in the esophagus and stomach which may lead to reflux of stomach content upwards and infant may vomit also.
High impact exercises like running, weight lifting, and eating before exercise may trigger acidity problems by relaxing your lower esophageal opening. Due to this, stomach acid or food in the stomach regurgitates upwards into the esophagus giving rise to heartburn. That does not mean you should stop exercising as losing weight may be an important strategy in preventing acidity. Consult your physician in choosing suitable exercise for you and to avoid eating just before exercise may be helpful.
Acidic foods and fruits, e.g., citrus fruits (lemon, orange), grapes, etc. may stimulate acid contents in the stomach giving rise to acidity problem. Banana is a low acid containing food that may be useful in patients of acidity or heartburn. Cucumber on the other hand is an alkaline food, hence usually does not cause acidity problem and can be taken.
Acidity may be an important cause of teeth damage and erosion. Due to excessive acid production and reflux, acids may come in contact with your teeth and damage the protective covering of enamel leading to erosion of teeth.
Acidity and acid reflux when severe and frequent may become a serious problem. In a long run uncontrolled acid reflux may give rise to erosion and ulcers in the esophagus. It may also cause narrowing of esophagus or esophageal strictures leading to difficulty in swallowing. In a few patients, long-term acid reflux may lead to changes in the lining of the esophagus called as Barrett’s esophagus which may convert to cancer of esophagus.
Coconut water or naariyal paani is usually alkaline hence neutralizes your acidic stomach and restores normal pH in the stomach. It also stimulates mucus production that protect from harmful effects of excessive acids. Coconut water is also rich in fibers that helps in digestion of foods and reduces acidity.

In fact, green apple is more acidic than red apple and it is observed that few people eating green apple may experience worsening of acidity and reflux symptoms due acid contents in it.
Antibiotics such as tetracycline may cause irritation of linings of esophagus and cause heartburn. Antibiotics may also exaggerate gastrointestinal reflux symptoms in which stomach acid refluxes back into esophagus causing acidity problems.
Chocolate contains caffeine, cocoa, and other stimulants that may trigger acid reflux. Chocolates may also lead to incomplete closure of your lower esophagus pushing stomach contents into the esophagus called as regurgitation. This may present as heartburn and acidity.

When these linings get damaged, acid may get through these linings leading to ulcer formation and increased acidity.
Apple cider vinegar is a special type of vinegar that is used to prevent acid reflux. As it contains vinegar or acetic acid, it may kills harmful bacteria in the stomach which are involved in causing ulcer. Composition of apple cider vinegar closely resembles that of normal acid content of the stomach, so it balances the stomach environment and may help in reducing acidity symptoms. Add 1 tablespoon apple cider vinegar to a glass of water and drink daily before meal.
Tea and coffee contains caffeine that may lead to acid reflux due to relaxation of lower esophageal opening. Milk is a very important dairy product used to strengthen your bone, but sometimes it may lead to acidity especially when whole milk or fat milk is used. Fat milk may trigger production of acid and may cause slow stomach emptying exaggerating the reflux symptoms. Skim milk may be better to consume than fat milk in acidity. Curd or yoghurt on the other hand may contain probiotics or useful bacteria that helps in digestion and may be helpful in acidity.
Acidity is excess production of acids in the stomach by glands present in it. Acidity is a symptom of some diseases especially gastroesophageal reflux disease (GERD) in which acids from stomach regurgitates into esophagus leading to burning sensation or heartburn. Esophageal pH testing is used to measure acidity in which a probe is inserted via nose into the esophagus which is then connected to a monitor to measure acid production.
Most of the chicken noodle soup contains fatty chicken and fat is a known trigger for developing acid reflux leading to acidity. Hence, chicken noodle soup is usually acidic. Few types of chicken noodle soup contains low fats that may not trigger acidity.
Acidity in ayurveda is called ‘amla pitta’ (amla means sour and pitta means heat). Apart from lifestyle modifications and avoiding acid triggering foods, Ayurveda also mentions usefulness of several herbs and natural ways to prevent and treat acidity. Some of these include drinking water with cardamom (improves digestion), extract of tulsi leaves (relieves acidity and gas and helps in ulcer healing), clove buds (improves movements in digestive tract), jeera water (improves digestion and prevent gas formation), pudina or mint leaves (reduces acidity). Consult your ayurvedic doctor to know suitable remedy for treating and preventing acidity problem.
