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 direct and well understood, but it is rarely explained to patients before they start treatment.

The mechanism

GLP-1 medications slow gastric emptying throughout the entire digestive system. 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 gastric emptying is a sustained effect of the medication. Reduced food intake also remains constant, meaning the lack of dietary fiber does not resolve 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. One of the most evidence-backed fiber interventions for constipation and compatible with long-term use.

Magnesium. Draws water into the intestine and supports smooth muscle contractions in the colon. Magnesium deficiency, common during GLP-1 treatment, is itself a contributing cause of constipation.

Hydration and electrolytes. Adequate fluid and electrolyte intake is a prerequisite for normal bowel function.

The TAKE approach

TAKE Flow delivers psyllium husk alongside ginger root and digestive enzymes. TAKE Hydrate addresses the electrolyte deficit that compounds GLP-1-related constipation. Both form the core of The Gut Reset System.
