Acidity home remedies: what helps, what does not, and when to see a doctor
The home measures with the strongest evidence for acidity are not kitchen ingredients. They are an earlier and smaller dinner, raising the head end of the bed, sleeping on the left side and losing weight around the waist. Traditional remedies such as cold milk, buttermilk or fennel soothe some people for a while. A few popular remedies can make reflux worse.
In short
- Timing, portion size, sleep position and weight have the most evidence.
- Kitchen remedies may soothe. None has been shown to heal an inflamed food pipe.
- Avoid baking soda, vinegar and mint.
- Acidity that occurs twice a week or more, or comes with warning signs, needs a medical assessment.
What has good evidence?
Eat dinner earlier
Leave three hours between your last meal and lying down. Reflux at night is strongly linked to late meals.
Eat less at a time
A very full stomach pushes its contents upward. Smaller meals, eaten slowly, reduce reflux.
Raise the head end of the bed
By 15 to 20 centimetres, with blocks under the legs of the bed or a wedge under the mattress. Stacking pillows bends the body at the waist and does not help.
Sleep on your left side
In this position the stomach lies below the food pipe, and less acid flows back.
Lose weight around the waist
Of all the lifestyle measures, this has the largest effect over time.
Stop smoking
Tobacco weakens the valve at the top of the stomach.
What about kitchen remedies?
| Remedy | What can be said |
|---|---|
| Cold milk | Brief relief for some. A large glass at bedtime can worsen night-time reflux. |
| Buttermilk or curd | Soothing and easy on the stomach. No trials in reflux. |
| Banana, coconut water | Gentle on the stomach. No evidence of harm or of specific benefit. |
| Fennel (saunf), cumin (jeera), carom (ajwain) | Traditionally used for gas and fullness after meals. Evidence in reflux is lacking. |
| Ginger | May ease nausea and fullness. Large amounts can cause heartburn. |
| Chewing gum after meals | Increases saliva, which neutralises acid in the food pipe. Small studies suggest a benefit. Avoid mint flavours. |
These are reasonable to try in moderation. If one helps you, continue it. None is a substitute for treatment when the food pipe is inflamed.
Which remedies should I avoid?
Baking soda
It neutralises acid for a few minutes, but it carries a large load of sodium and is harmful with regular use, especially with high blood pressure, kidney disease or heart disease.
Vinegar and lemon water
Both are acidic. There is no evidence that they help, and they can irritate an inflamed food pipe.
Mint
Peppermint relaxes the valve at the top of the stomach and can worsen reflux, although it helps some bowel symptoms.
Lying down after a meal
A short walk is better.
Antacids every day for months
Frequent use hides a problem that deserves a diagnosis.
Is my acidity really acidity?
Several conditions are described as “acidity” and behave differently:
- Reflux: burning that rises into the chest, worse on lying down. See acid reflux.
- Gastritis or an ulcer: pain in the upper abdomen, related to meals. See gastritis.
- Functional indigestion: fullness and discomfort with normal tests.
- Gallstones: attacks of steady pain under the right ribs after meals.
- Heart pain: pressure in the chest with exertion, sweating or breathlessness. This is an emergency.
The remedy that suits one does not suit the others, which is why persistent symptoms need a diagnosis.
When should I see a doctor?
See a doctor if you have
- Acidity twice a week or more for over a month
- Symptoms that return as soon as you stop medicine
- Difficulty or pain on swallowing
- Vomiting, weight loss or a poor appetite
- Black stools or vomiting of blood
- Acidity that begins for the first time after the age of 45
Chest pain with sweating or breathlessness needs an emergency department.
Questions patients ask me
Which food neutralises stomach acid immediately?
No food reliably does. Milk, banana and plain rice are gentle and may ease the burning for a short time. An antacid acts within minutes if you need quick relief on occasion.
Is drinking warm water in the morning good for acidity?
It is harmless and comfortable for many people. There is no evidence that water temperature affects reflux.
Can I take antacids every day?
For a few days, yes. If you need them daily for more than two weeks, see a doctor. The cause should be identified and treated.
Does fasting cause acidity?
Long gaps between meals bring on upper abdominal burning in some people, and breaking a fast with a very large meal causes reflux. Regular, moderate meals suit most people with acidity.
