Dr. Crystal is an OB Hospitalist at El Camino Hospital covering emergencies for all patients in Labor and Delivery at either the Mountain View or Los Gatos hospital locations for any physician or midwife. Because of this, Dr. Crystal has agreed not to see pregnant patients in the office after the first trimester because of a conflict of interest with her other hospital position.
Dr. Crystal will be happy to see you for your first OB visit at 8 weeks gestation and then you would follow up with our other physicians Dr. Teng and Dr. Azad for the rest of your pregnancy.

Constipation in Pregnancy
Constipation is very common in pregnancy because the hormone progesterone tends to slow down bowel function. Constipation and straining with bowel movements increases the risk of hemorrhoids.
First Line Therapy:
- Increase water intake
- Increase foods with fiber and try prunes if you are not diabetic
- Exercise such as walking can help the bowels to move regularly
- Metamucil in a big glass of water 1-3x/day
Second Line Therapy:
- Colace (DSS or Docusate Sodium)- 100mg-250mg 1-2x/daily. (There has been a report of a baby with low Magnesium levels in a mother who took more than the recommended dose.)
- Lactulose- by prescription
- Glycerine rectal suppository- No human studies, but per CTIS there are no reports of problems either. Very high i.v. doses caused fetal problems in rabbits.
- Senna laxatives (Ex-Lax)- probably ok but theoretical risk of uterine contractions so only use if you ask your doctor.
