Abdominal discomfort from Ovarian Hyperstimulation Syndrome

Ovarian Hyperstimulation Syndrome [OHSS] is when the ovaries swell and retain fluid due to the injectable hormones that help to stimulation the development of eggs in the ovaries. Symptoms include vomiting, nausea, weight gain, abdominal discomfort, bloating,  and shortness of breath.


Women who have a lower body weight, PCOS, have a high AMH, or have had a fresh embryo transfer are more likely to develop OHSS.


Generally, OHSS is mild and usually resolves in 2 weeks but for approximately of 20% of women, it may take up to a month to resolve. OHSS can be more severe in some women and may require hospitalisation. If you do become pregnant, symptoms are likely to remain a little longer.


Nutrition to Help Prevent OHSS after transfer

  • Hydration, 2L per day (An electrolyte drink or coconut water can be helpful)
  • Sodium, add a little extra sprinkle of salt to foods post retrival
  • Avoid intense workouts (light, slow walks are ok and stretching)


Nutrition to Help Treat OHSS

Manage hydration

  • Aim for 2-3L of water per day.
  • If vomiting, try to get from more solid foods like soups, or jelly as easier to keep down. Sucking on ice cubes can also help.
  • If you are losing fluids, you need to replace them. If you aren’t processing fluids well, you may need to restrict temporarily.

Grate ginger into foods or drinks or make ginger tea to help allievate nausea.

If you are retaining fluids, you need to restrict sodium.

  • Don’t add salt to foods
  • Choose low sodium foods
  • Avoid food high in sodium like potato chips or crackers

Eat small, frequent meals.

  • Your diet doesn’t have to be perfect. Think toast, a piece of fruit, smoothies, cereal and vegetable soups.


If OHSS symptoms become severe or progresses longer than expected, medical management may be indicated.
