Will Iberogast help with indigestion, diarrhea and heartburn? Could it be reflux?

Unfortunately, I am not able to answer whether you should use any more medicine without knowing what medications you are currently using. First of all, if you have ever been treated for gastroesophageal reflux disease and now the symptoms are recurring, it is worth going to the doctor to check your health. Heartburn (acid in the mouth) or indigestion, abdominal pain, diarrhea can of course be related to the recurrence of this ailment. Iberogast is an aid in indigestion, flatulence, etc., but it does not work on symptoms such as diarrhoea. The treatment of diarrhoea (i.e. a condition when stools of excessively loose consistency (liquid or semi-liquid) appear with increased frequency (at least 3 times a day)) consists primarily of hydration. Electrolytes can be purchased without a prescription at a pharmacy or ordered online using GdziePoLek, e.g.: https://www.gdziepolek.pl/produkty/57955/orsalit-smak-neutralny-proszek-do-wytworzenia-zawiesiny/apteki?pvid=215782#internetowe We wrote more about the treatment of diarrhea and measures that can be used outside of hydration here: https://www.gdziepolek.pl/artykuly/jak-zwalczyc-biegunke If the situation described by you is not related, for example, to overeating, indigestion, but rather a relapse of the disease Reflux disease and symptoms persist for several days and even worsen - it is worth consulting a doctor.
