I'm sorry to hear that you're experiencing indigestion, loose motions, headaches, and general weakness. These symptoms could be related to an infection or gastrointestinal upset, among other causes.

Given the combination of symptoms, it is important to:

• Stay hydrated by drinking plenty of fluids to prevent dehydration, especially with loose motions.
• Avoid heavy, spicy, or oily foods until symptoms improve.
• Rest as much as possible to help your body recover.
• Monitor your symptoms closely for any worsening, such as high fever, severe abdominal pain, persistent vomiting, or blood in stools.

Since these symptoms can be caused by infections that sometimes require specific treatment, it is important to consult a doctor, preferably a general physician or a gastroenterologist, who can evaluate your condition properly. They may recommend investigations or prescribe appropriate medications if needed.

If you are currently taking any medications like antibiotics (for example, Ofloxacin), be sure to inform your doctor, as some side effects of such drugs can include gastrointestinal upset and headaches.

If your symptoms worsen or you experience difficulty breathing, severe weakness, or confusion, seek emergency medical care immediately.
