In short

Treatment of a slow stomach is a sequence. First fix the causes you can fix. Then change the food. Then add a medicine.

Small, soft, low-fat meals help most. Liquids pass more easily than solids, so they can fill the gap when solid food will not stay down.

Each medicine has a limit. Metoclopramide is for short courses. Domperidone and erythromycin need a heart tracing. Your doctor sets the dose and the time.

All the treatment options, including the pyloric procedures, are set out on the gastroparesis treatment in Ahmedabad page. This post covers the first steps: food and medicines.

Fix the causes you can fix first

Before any new tablet, look for what is slowing the stomach. Some causes can be removed. This step is missed often.

  • High blood sugar slows the stomach and blunts the effect of medicines. Better sugar control comes first.
  • Opioid painkillers slow the stomach. They can be cut down or swapped.
  • GLP-1 injections for diabetes or weight loss slow the stomach. The slowing eases when they are stopped or reduced.
  • Some other tablets also slow the gut. Examples are anticholinergics and certain blood pressure medicines.
  • Low potassium or magnesium, and lack of fluid, make the gut weaker. These are corrected.

Many people called “resistant” have not yet had this step done. How the problem is confirmed is explained on the post about how gastroparesis is diagnosed.

Food a slow stomach can handle

Food is the first treatment and the safest one. Small, soft, low-fat meals ask less of a weak stomach.

Food rules and why they help
RuleWhy it helps
Four to six small meals a dayLess food for the stomach to clear at one time
Low fat, especially solid fat such as ghee and fried foodFat slows the stomach
Low in tough fibre, such as raw salad, skins and seedsLess leftover residue, and a lower chance of food balls
Soft, mashed or blended foodSmall particles leave the stomach more easily
Sit upright and walk a little for one to two hours after a mealGravity helps emptying
Enough fluids, and a vitamin checkPoor intake lowers iron, B12 and vitamin D

A trial in people with diabetes showed that a small-particle diet eased nausea, vomiting, fullness and bloating. A dietitian helps you keep it up and keeps nutrition adequate.

When solid food will not stay down

Liquids leave the stomach by a different route that is often still working. More of your calories can come as liquid or semi-solid food.

  • Soups, smoothies, milk-based drinks and nutrition drinks are tried first.
  • Go back to solid food slowly as the symptoms settle.
  • If intake keeps falling, a feeding tube into the small bowel is tried before any drip into a vein.
  • Weight, blood tests and urine output are watched. This is covered in the post on gastroparesis complications and follow-up.

Medicines that speed up the stomach

These medicines are called prokinetics. They make the stomach empty faster. The relief of symptoms is smaller and less certain than the change in emptying.

Common prokinetic medicines compared
MedicineHow it worksMain caution
MetoclopramideSpeeds emptying and calms nauseaMovement side effects; short courses only
DomperidoneSpeeds emptying; does not act on the brainHeart rhythm; ECG needed
ErythromycinStrong trigger for stomach contractionsEffect fades; heart rhythm; many drug interactions
PrucaloprideActs on gut nerve receptorsUsed off-label for this problem
Levosulpiride, itoprideWidely used in IndiaFewer good trials; levosulpiride has movement and hormone effects

A medicine is taken before meals, usually in liquid form where possible. If a tablet is vomited, a liquid or another route may work better.

Metoclopramide: short courses only

Metoclopramide is the main approved medicine for this problem. It helps nausea and emptying. It can also cause movement problems that may not go away.

  • The lowest dose that works is used, before meals.
  • Courses are kept short. Many doctors aim for about three months at most.
  • Tell your doctor at once about twitching, stiffness, restlessness or tremor. Stop the medicine first, then call.
  • Low mood and sleepiness can also occur.
  • A nasal spray form exists abroad. It is hardly available in India.

Domperidone and the heart check

Domperidone does not reach the brain in a meaningful way, so it spares you the movement problems. Its risk is to the heart rhythm.

  • An ECG is done before starting, and again during treatment.
  • It is held back if the heart tracing already shows a long interval.
  • It is avoided in heart disease and with other medicines that affect the rhythm.
  • In India it is sold without a prescription. That is convenient, but the same checks apply.
  • Do not raise the dose on your own because it feels weak.

Erythromycin, prucalopride and others

Erythromycin is the strongest short-term prokinetic. It suits a hospital stay during a flare. Over weeks, the effect fades.

  • Given by a drip in hospital, it can settle a bad spell quickly.
  • By mouth, a low-dose liquid before meals is used for a few weeks.
  • It affects the heart rhythm and mixes badly with many other drugs. Check every new medicine with your doctor.
  • Prucalopride is an option when the usual drugs fail or are not suitable.
  • Newer drugs, such as relamorelin, are not yet standard and are hard to get here.

Medicines for nausea and mood

Some people have mostly nausea, with near-normal emptying. In them, medicines for nausea carry the load.

  • Anti-sickness tablets are used when nausea is the main trouble. Some also affect the heart rhythm.
  • Nortriptyline did not help in a large trial of people with no clear cause. It is not a routine choice.
  • Aprepitant has given mixed results.
  • Anxiety and low mood are common with long illness. Treating them improves day-to-day life.

When medicines are not enough

A procedure is considered only after food changes and a proper medicine trial have failed. A proper trial means the right dose, for long enough.

  • Keep a simple diary of symptoms, weight and the medicines tried.
  • The choice then depends on the pattern: a tight outlet, weak muscle, or poor nutrition.
  • Options include an endoscopic procedure on the outlet, a stomach stimulator, or a feeding tube.
  • These are described on the gastroparesis treatment page.

Questions to ask at your visit

  • Is any tablet or injection of mine slowing my stomach?
  • Which food changes should I start this week?
  • Do I need an ECG for the medicine you suggest?
  • How long should I take it, and how will we judge if it works?
  • What is the plan if it does not work?

Frequently asked questions

What is the first treatment for a slow stomach?

Fix the causes you can, such as high sugar, opioids and GLP-1 injections. Then change the food. Medicines come after that.

Which foods suit a slow stomach?

Small, soft, low-fat meals eaten often. Blended food and liquids pass more easily than raw salad or fried food.

How long can metoclopramide be taken?

Only for short courses, often about three months at most. Your doctor sets the limit.

Why is an ECG needed with domperidone?

It can change the heart rhythm. An ECG is done before and during treatment.

Do nortriptyline or anti-nausea tablets fix the stomach?

They calm symptoms but do not speed the stomach. They help when nausea is the main trouble.

When is a procedure considered?

After food changes and a proper medicine trial have failed. A proper trial is the right dose for long enough.
