Constipation at ~4 weeks pregnancy
If there is no severe abdominal pain, vomiting, abdominal distension, fever, rectal bleeding, or inability to pass gas, constipation can usually be managed conservatively.
1. First-line
Adequate fluids.
Fiber-rich diet: fruits, vegetables, whole grains, oats, dal, etc.
Regular gentle physical activity.
Don't delay the urge to defecate.
A semi-solid diet is not routinely required; normal balanced pregnancy diet with adequate fiber is preferable.
2. Laxative If dietary measures are insufficient, commonly used options include:
Psyllium/ispaghula (bulk-forming) – good first option.
Lactulose or PEG/macrogol – commonly used osmotic laxatives when needed.
Avoid unnecessary stimulant laxative use as a routine first step.
3. Rectal enema I would not routinely give an enema simply because there has been no stool for 3 days. If there is significant fecal impaction or severe refractory constipation, rectal treatment may sometimes be considered after clinical assessment, but in early pregnancy it is preferable to use the least invasive effective approach.
