Problems With Glucomannan

Although it's been used in Eastern countries for over 1,000 years, glucomannan has only become popular in the West in the past 20 years. Obtained from the konjac plant root, it is a highly fibrous substance that can ease constipation and aid in weight loss, as it provides a feeling of satiety and fullness for those taking it. However, there are a few significant concerns that should be considered by anyone taking glucomannan.

  1. Esophageal and Abdominal Obstruction

    • There have been documented cases of people taking glucomannan tablets and suffering from severe throat and gastrointestinal tract obstruction, as the tablet can create a blockage that is not easily removed. For this reason, capsules are recommended over tablets, and those who have difficulty swallowing in general should not take glucomannan.

    Issue for Diabetics

    • Glucomannan is known to reduce the level of sugar in the blood, making it especially important for diabetics to consult their physicians beforehand and monitor their blood sugar levels closely while using it.

    Discomfort

    • Those taking glucomannan may experience flatulence, bloating, nausea, diarrhea and abdominal pain. These are generally not serious issues but can be very uncomfortable.

      Some people may have allergic reactions to glucomannan, including a rash, hives or general itching.

    Interference With Medications

    • Glucomannan can decrease or delay the absorption of medication into your bloodstream, so it's best to take your medication one hour prior, or four hours after, taking glucomannan.
