What Reddit Users Report About Retatrutide Constipation
Constipation is one of the most discussed side effects on the retatrutide subreddits. Users typically report that constipation begins within the first week of starting the drug or within the first few days after a dose increase. The pattern matches the clinical trial data — 15-20% of participants report constipation — but the Reddit discussions provide practical management strategies that the clinical trials did not test. The most commonly recommended approaches include increased water intake, fiber supplements, magnesium citrate, and polyethylene glycol.
User-Tested Relief Strategies
The most frequently recommended strategy on Reddit for retatrutide constipation is magnesium citrate, taken as a daily supplement of 200-400 mg. Users report that it is gentle enough for daily use and does not cause the cramping that stimulant laxatives can produce. Psyllium husk fiber supplements are the second most recommended option, though some users note that fiber without adequate water can worsen constipation — the fiber needs water to work. Polyethylene glycol is recommended for acute relief but not daily prevention.
