From the Guidelines

Feeling sleepy after H. pylori treatment despite adequate sleep is generally not worrisome and is a common side effect of the medications used. The treatment for H. pylori, which typically involves a combination of antibiotics and a proton pump inhibitor, can cause fatigue and drowsiness as the body works to fight the infection and deal with the medication's effects 1. The antibiotics used in H. pylori treatment can disrupt the gut microbiome, affecting energy levels, and some medications like metronidazole can directly cause drowsiness.

Some key points to consider in the management of functional dyspepsia, which may be related to H. pylori infection, include:

  • Eradication therapy is an efficacious treatment for H. pylori-positive patients with functional dyspepsia, although adverse events are more common than with control therapy 1.
  • Proton pump inhibitors are an efficacious treatment for functional dyspepsia and are generally well-tolerated, with the recommendation to use the lowest dose that controls symptoms 1.
  • Regular aerobic exercise is recommended for patients with functional dyspepsia, despite the quality of evidence being very low 1.

To manage the side effect of fatigue during H. pylori treatment, it is essential to:

  • Stay hydrated by drinking plenty of water
  • Eat nutritious meals to help the body recover from the infection and the medication's effects
  • Avoid alcohol during treatment, as it can exacerbate fatigue and other side effects

If the extreme fatigue persists more than a week after completing treatment, or if it's accompanied by severe symptoms like high fever, intense abdominal pain, or inability to keep food down, then it would be appropriate to contact a healthcare provider for further evaluation.

From the Research

Patient Concerns

  • The patient reports feeling sleepy after H. pylori treatment despite getting 9 hours of sleep.
  • This symptom is worrisome and may be related to the treatment or the eradication of H. pylori.

Treatment Side Effects

  • The studies provided do not directly address the issue of sleepiness as a side effect of H. pylori treatment 2, 3, 4, 5, 6.
  • However, it is known that antibiotic treatment can lead to changes in the intestinal microflora, which may cause various side effects, including fatigue or sleep disturbances 6.
  • The study by 6 found that the intestinal microflora returned to normal after 4 weeks of therapy, which may suggest that any side effects related to the treatment are temporary.

H. pylori Treatment

  • The standard treatment for H. pylori infection typically includes a combination of antibiotics and a proton pump inhibitor 2, 3, 4, 5.
  • The choice of antibiotics and the duration of treatment may vary depending on the specific regimen and the patient's response to treatment.
  • The studies provided suggest that different treatment regimens, such as PAC (proton pump inhibitor, amoxicillin, and clarithromycin) and PAM (proton pump inhibitor, amoxicillin, and metronidazole), have similar efficacy in eradicating H. pylori 5.

Next Steps

  • It is recommended that the patient consult with their healthcare provider to discuss their symptoms and determine the best course of action.
  • The healthcare provider may consider adjusting the treatment regimen or recommending additional tests to rule out any underlying conditions that may be contributing to the patient's sleepiness.
