Managing Pregnancy Constipation: A Guide to the Best Fiber Supplements

Written by Andrew Le, MD

UpdatedNovember 13, 2024

Constipation is a common problem experienced by pregnant women mainly because of increased pressure on the digestive system as well as hormonal changes. This uncomfortable condition can lead to discomfort, bloating, and even hemorrhoids, making it challenging for expectant mothers to go about their daily activities. It has been estimated that approximately 11% to 38% of pregnant women experience constipation, which is generally described as infrequent bowel movements.

Dealing with constipation during pregnancy can be frustrating and overwhelming, especially when over-the-counter medications may not be the safest option. Relying solely on dietary changes might not provide sufficient relief, leaving pregnant women searching for effective and gentle solutions.

Fortunately, incorporating the best fiber supplements for pregnancy can alleviate constipation by promoting regular bowel movements and supporting overall digestive health. These carefully formulated products offer a safe and convenient way to increase fiber intake, ensuring expectant mothers can navigate this crucial period.

Mechanism of Action of Fiber among Pregnant Women

Fiber supplements significantly address constipation during pregnancy by increasing stool bulk and facilitating easier passage. This mechanism involves binding luminal water, which augments stool volume and aids its movement through the intestines.

Specifically, substances like psyllium and bran are typical examples of bulk-forming agents that are often recommended as the best fiber supplements for pregnancy due to their non-systemic absorption and relative safety profile.

Efficacy of Fiber Supplements for Constipation in Pregnancy

One study indicates that dietary fiber, specifically resistant starch (PRS), effectively alleviates constipation in late pregnancy by enhancing gut motility. This effect was observed in a model using pregnant sows. PRS improved defecation frequency and fecal consistency more significantly than other fiber types tested, such as lignocellulose and konjaku flour.

Physiologically, PRS and konjaku flour increased serum levels of gut motility regulatory factors like 5-hydroxytryptamine (5-HT), motilin (MTL), and acetylcholinesterase (AChE), which are known to enhance intestinal movements. Additionally, these fibers modulated inflammatory responses by increasing anti-inflammatory IL-10 and decreasing pro-inflammatory TNF-α levels.

Microbial sequencing revealed that PRS and konjaku flour beneficially adjusted the gut microbiota. They increased the abundance of short-chain fatty acid (SCFA)- producing bacteria such as Bacteroides and Parabacteroides and decreased endotoxin-producing bacteria like Desulfovibrio and Oscillibacter. PRS specifically raised Turicibacter and fecal butyrate levels, which correlated positively with increased defecation frequency and serum 5-HT levels.

The findings suggest that incorporating resistant starch in the diet during late pregnancy could be a viable strategy to mitigate constipation through its positive effects on gut motility and microbiota composition. This non-pharmacological approach could be particularly appealing for managing pregnancy-related constipation, pending further validation in human clinical trials.

Safety and Side Effects

Fiber supplements are generally considered safe for alleviating constipation during pregnancy, but there are important considerations regarding their use. Pregnant women with specific dietary needs or health conditions, such as diabetes or those taking certain medications, should consult their healthcare providers before starting fiber supplements.

Fiber can interact with medicines by reducing or delaying their absorption, which is particularly important for tricyclic antidepressants, diabetes medications, carbamazepine, cholesterol-lowering medications, digoxin, and lithium.
