Treatment Options

Treatment options for functional dyspepsia generally include one or a combination of:

  • Diet
  • Eradication of H. pylori
  • Acid-lowering medications
  • Prokinetic and antiemetic agents
  • Centrally acting therapies

Diet – Most patients with FD have symptoms associated with the ingestion of food. As such, a variety of dietary recommendations are often made, although no clinical trials have formally evaluated specific dietary interventions for the treatment of FD. There are limited data to suggest that dietary fat may induce or exacerbate symptoms and patients often report improvement by eating low-fat meals, and more frequent, smaller meals.

Eradication of H. pylori – Although testing and treating H. pylori infection is recommended and often employed, the eradication of H. pylori infection generally does not improve symptoms outside of those associated with peptic ulcer disease. In patients with FD, there is little benefit beyond placebo in eradicating H. pylori infection and a recent analysis found that only one out of every fourteen H. pylori-infected patients with FD would benefit from treatment.

Acid-lowering Medications – H2 blockers such as ranitidine (Zantac)**, cimetidine (Tagamet), nizatidine (Axid) or famotidine (Pepcid) are the initial agent used by many primary care providers, and are marginally better than placebo at improving upper-center abdominal (epigastric) pain, although they do not improve other dyspeptic symptoms.

If H2 blockers fail to improve symptoms, most doctors then use a proton pump inhibitor (PPI) – omeprazole (Prilosec), lansoprazole (Prevacid), rabeprazole (Aciphex), pantoprazole (Protonix), or esomeprazole (Nexium). Short-term risks of this strategy are low, and this may provide relief of symptoms in a small number of people, many of whom may have had silent acid reflux. As a group, PPIs are approximately 10% better than placebo at improving dyspeptic symptoms. However, long-term use of PPIs can be expensive.

There is emerging data suggesting that long-term PPI use – when combined with other risk factors – may place some patients at increased risk for Clostridium difficile colitis, community acquired pneumonia, and hip fractures. Nonetheless, overall risk of long-term PPI use seems to be relatively small.

Prokinetic and Antiemetic Agents – Patients with nausea will respond to medications that target that specific symptom. Limited data suggests that symptoms of early feeling of fullness, upper abdominal fullness, and discomfort after eating may respond to the use of medicines that increase gastrointestinal motility (prokinetic agents). The drugs metoclopramide (Reglan) and domperidone (Motilium) are now the most commonly employed agents.

Unfortunately, metoclopramide often has significant side effects including anxiety, drowsiness, decreased libido, and breast tenderness as well as movement disorders. Talk to your doctor before you use metoclopramide. The FDA requires a boxed warning and risk mitigation strategy for metoclopramide-containing drugs. Read more here.

Domperidone is not commercially available in the United States although it is widely used throughout much of the rest of the world. The utility of prokinetic therapy in functional dyspepsia, to date, is largely unproven.

Centrally Acting Therapies – Much of the control of digestive function and sensation is under central nervous system guidance; therapies that target central control mechanisms may have value in relieving symptoms. Tricyclic antidepressants, used in doses lower than required to treat depression, may improve symptoms of dyspepsia in patients who have failed to benefit from treatment with H2 blockers or prokinetics. 

Another type of antidepressant, selective serotonin reuptake inhibitors (SSRIs), have not been well studied for the treatment of FD, however they appear effective in the treatment of other functional digestive disorders.

Hypnotherapy may improve dyspeptic symptoms in some patients, and a recent study found that hypnotherapy was better than medical therapy and supportive therapy at improving quality of life and symptom scores. Although not well studied, psychological therapies, including cognitive behavioral therapy, may also relieve symptoms of dyspepsia.


Functional dyspepsia is a common digestive disorder that remains poorly understood. Ongoing investigations seek to define causes and effective therapies. Currently, the National Institutes of Health (NIH) is sponsoring a nationwide, multi-center study that hopes to better define causes and treatments for FD.
