Why am I constipated on Wegovy or Ozempic?

Constipation is one of the most commonly reported GLP-1 side effects and one of the most predictable. The mechanism is well described, but it is rarely explained to patients before they start treatment.

The mechanism

GLP-1 medications slow movement through the digestive tract, not just the stomach. Slower intestinal transit means the colon absorbs more water from stool, making it harder and more difficult to pass. Combined with significantly reduced food intake, which means less fiber and less of the natural digestive stimulation that food volume creates, the result is predictable constipation.

Why it persists

Unlike nausea, which often improves after the body adjusts to a new dose, constipation can persist throughout treatment because slowed transit is a sustained effect of the medication. Reduced food intake also remains constant, meaning the lower fiber intake does not resolve on its own over time.

What the evidence supports

Psyllium husk fiber. Absorbs water and forms a gel in the intestine, adding bulk and moisture to stool and supporting regular transit.* It is among the better studied fiber interventions for constipation and is compatible with long-term use. Meta-analytic work points to 10g of psyllium daily or more as the optimal intake for chronic constipation, which is worth knowing when reading any fiber label, including ours. It must be taken with a full glass of water, and kept at least two hours apart from medication, since it can slow absorption.

Magnesium. Draws water into the intestine and supports smooth muscle contraction in the colon.* Magnesium intake commonly falls when eating less, and low magnesium can contribute to constipation. If you suspect your intake is low, bloodwork and a conversation with your clinician are more useful than guessing at a dose.

Hydration. Adequate fluid is a prerequisite for normal bowel function. Fiber without fluid tends to make constipation worse rather than better.

The TAKE approach

TAKE Flow provides 3,000mg of psyllium husk per sachet alongside tamarind, a digestive enzyme blend and a small amount of ginger root extract, and is formulated to support digestive regularity.* At that dose it is daily support alongside dietary fiber rather than the 10g the constipation literature points to on its own. Take it at least two hours away from any medication. Flow is made in Latvia.

TAKE Hydrate is a light electrolyte load, 100mg sodium and 200mg potassium per scoop, formulated to make drinking enough through the day easier.* It is not a treatment for constipation, and it is not a substitute for the fluid itself. Flow and Flora form the core of The Gut Reset.
