What is PCOS?
Polycystic ovary syndrome (PCOS) is a common condition and affects approximately 7 in 100 women.
What are the symptoms of PCOS?
- Irregular, infrequent periods or no periods at all
- Infertility (due to irregular or no ovulation)
- Excessive hair growth (hirsutism) on the face, chest or back
- Weight gain
- Hair loss from the head
- Oily skin or acne
How do you diagnose PCOS?
Any two out the following three features would be diagnostic.
- Ovaries have many (more than 12) tiny cysts: These cysts are small blister-like-lumps (about 5-8 mm) that form on the surface of the ovaries. Women produce an egg every month and these eggs, if not released, may be retained as small cysts. This is usually seen on an ultrasound scan. The polycystic appearance of ovaries is seen on ultrasound scan in 22% of women but only a few of these women will have the “syndrome”.
- Hormonal imbalance (Hyperandrogenism): Ovaries produce the “female” hormones, such as oestrogen and progesterone and also very small amount of the “male” hormone, testosterone. When the level of testosterone in the blood goes over a certain level, it can cause some of the common symptoms of PCOS like acne and unwanted hair growth.
- Failure to ovulate every month (anovulation) leading to infrequent or absent periods: Oligomenorrhoea means less than six periods in a year and amenorrhoea means no periods at all.
Does PCOS affect fertility?
Although around 60% of women with PCOS achieve spontaneous pregnancy without any medical help, some women can struggle with ovulation and may need help. Usually, this is quite simple in the form of medication and scans.
Can diet and nutrition help PCOS
A healthy eating plan can help manage and alleviate some PCOS symptoms. The right diet will have a positive impact on blood sugar and insulin management, as well as helping with cell sensitivity and hormone balance.
Decrease or Eliminate:
It is important to remember that due to insulin resistance, PCOS women are not able to deal with simple carbs. Hence it is important to avoid the following:
- Sugars: White refined sugar, artificial sweeteners etc
- Natural sweet sugars: Honey, dates, agave, too much fruit
- Carbohydrates (High Glycemic Index): White bread, white rice, white pasta
Eat Plenty of:
- ‘Low GI’ Diet: Foods containing low Glycemic Index such as brown bread, rice and pasta, sweet potatoes, traditional porridge or muesli
- ‘Good’ fats: Nuts, seeds, cold pressed oils, oily fish, avocado and coconut
- Green leafy vegetables: Spinach, broccoli, kale, asparagus, rocket, broccoli, Sprouts
- Proteins: are OK with PCOS
A gynecologist or dietician can help with a healthy eating regime and exercise. Another positive effect of this lifestyle change can be to reduce the risk of diabetes, high blood pressure and heart disease in later life.
