Adding a small amount of ground flaxseed to your daily diet may help reduce bloating caused by constipation, according to WebMD. Flaxseed is a good source of dietary fiber, which helps promote regular bowel movements.
As of 2015, there is insufficient scientific evidence to fully support flaxseed's laxative effects; however, anecdotal evidence suggests that regular consumption of ground flaxseed increases the frequency of bowel movements in young adults and the elderly. This research looked specifically at young adults who ate muffins with flaxseed and at elderly patients who ate yogurt with flaxseed, reports WebMD
Bloating is often caused by excess gas that builds up in the stomach and intestines due to slowed digestion and constipation, notes StomachBloating.net. Eating ground flaxseed can help relieve this type of uncomplicated bloating.
Persistent or chronic bloating may be a sign of a more serious condition, such as an enlargement of one or more of the abdominal organs, notes WebMD. In this case, ground flaxseed is unlikely to stop the bloating. Taking ground flaxseed by mouth in normal food amounts is generally safe. Flaxseed may initially cause digestive symptoms such as gas, diarrhea, constipation and upset stomach. These symptoms tend to worsen with very high doses.
