What is Functional Dyspepsia?

Functional Dyspepsia, or FD (recurring indigestion with no known organic cause), is a relatively common, under-diagnosed, under-managed, and often frustrating condition.1,2 It is typically a meal-triggered disorder of sensation and movement in the organs of the upper digestive tract (above the navel). In FD, the normal downward pumping and squeezing is altered; this affects the digestion and absorption of food nutrients. It is estimated that one in six adults in the U.S. had FD.1 The condition can begin at any age and often reoccurs over time.

The primary symptoms of FD are in the upper belly and can include, at varying times, some or all of the following*:

  • Abdominal pain, discomfort, or cramping
  • Nausea
  • Difficulty finishing a meal
  • Burning
  • Bloating
  • Belching

It is thought that FD is associated with disruption in the lining of the gut (gut mucosal barrier).* Additionally, reversible, localized, low-grade immune activation can result in an impaired ability to digest and absorb food nutrients.2,3

Clinical studies have shown that the combination of caraway oil and peppermint oil (primary component: l-Menthol) can help manage the syndrome of FD symptoms.4 Until now however, targeted delivery to the upper belly has posed a challenge. FDgard is a medical food specially formulated for the dietary management of FD. FDgard utilizes breakthrough science through the precision of SST® (Site-Specific Targeting). This technology delivers individually triple-coated, targeted-release, solid-state microspheres of caraway oil and l-Menthol quickly and reliably to the upper belly.
