What is PCOS (Polycystic Ovary Syndrome)?

Polycystic ovary syndrome (PCOS) is an endocrine disturbance, caused by increased levels of testosterone, oestrogen, and luteinizing hormone (LH) and decreased secretion of follicle-stimulating hormone (FSH). Polycystic Ovary Syndrome (PCOS) affects about 5-15% of women of reproductive age. The syndrome affects premenopausal women and the age of onset is most often perimenarchal (before bone age reaches 16 years). In lean women with a genetic predisposition to PCOS, the syndrome may be unmasked when they subsequently gain weight.

Based on studies conducted in the UK, around one in twelve females have PCOS. NHS lists the three main features of the PCOS stating that at least two of the following must be met to give a diagnosis:

  • Irregular or infrequent periods – indication that ovaries do not regularly release eggs (ovulate)
  • Blood tests show high levels of ‘male hormones’ androgens, such as testosterone
  • Scan shows polycystic ovaries

How can a Nutritionist help with PCOS?

Working with a Nutritionist

Working with a Nutritionist can be transformative if you suffer from PCOS and struggling to lose weight. If you’re struggling to lose weight despite your best efforts, it may be time to seek professional help. You can get help from your Nutritionist in developing a personalised nutrition plan, identifying nutrient deficiencies, and help you in addressing any other underlying medical issues that might be negatively impacting your attempts to lose weight.

Your Nutritionist can work with you to develop a personalised nutrition plan that is catered to your unique needs and goals. The Nutritionist can also offer recommendations on the best supplements to take and lifestyle choices that can affect your weight, like getting enough sleep and managing your stress.

Book an appointment today if you feel like you need more assistance or direction to reach your goals.

Online consultation with a Nutritionist is available for clients who live outside the London area or who are unable to come to my office in Marylebone, Central London. You can enjoy the online consultation from the comfort of your home or office and you will be given the same level of personal attention and care that you would experience coming to see me in my Marylebone office.

My approach to dealing with PCOS

As a Nutritionist and Nutritional Therapist, when working with patients in my clinic in Harley Street, London, I take a holistic approach. Rather than suppressing the symptoms, I work on finding the root cause of PCOS and restoring the hormonal balance using diet, supplements and lifestyle. 

PCOS Symptoms

PCOS affects women in different ways and not all women will have all the associated symptoms. Symptoms usually starts in adolescence, however some women will not develop them until their early to mid-twenties. In many women, the only symptoms are either a failure to conceive or menstrual problems.

Common symptoms of PCOS include:

  • Weight gain, obesity or difficulty losing weight – especially around the middle (a common sign)
  • Oily skin or acne
  • Infertility or subfertility
  • Hirsutism (60% women with PCOS) especially on the upper lip, chin, around the nipples and in the line beneath the umbilicus.
  • Oligomenorrhoea (irregular periods)
  • Amenorrhea (no periods at all)
  • Alopecia –  male-pattern balding
  • Acanthosis nigricans (patches of thickened, dark, velvety skin) may be present. It is thought to be a sign of insulin resistance.
  • Occasionally- increased muscle mass, clitoromegaly and deep voice
  • Skin tags
  • Pain in the pelvic area, especially around the ovaries, including chronic pelvic discomfort as well as acute episodes of sharp pelvic pain that gradually resolves within a few hours or days.
  • Depression and mood changes.
  • Obstructive sleep apnoea

PCOS and Resistance to Insulin

PCOS is associated with peripheral insulin resistance and hyperinsulinemia, and obesity strengthens the degree of both abnormalities. Insulin resistance in PCOS has also been associated with adiponectin, a hormone secreted by adipocytes that regulates lipid metabolism and glucose levels. Levels of adiponectin are lower in lean and obese women with PCOS than in women without PCOS.

Insulin resistance is a condition in which the body’s tissues are resistant to the effects of insulin. The body in order to compensate has to produce extra insulin. Due to high levels of insulin, ovaries produce too much of testosterone, which interferes with the development of follicles and prevents normal ovulation.

When the body does not respond to insulin, blood glucose levels increase, which may cause more insulin to be produced as the body tries to move glucose into cells. Insulin resistance can lead to diabetes mellitus. It is also associated with accanthosis nigricans (patches of thickened, dark, velvety skin). Women with PCOS are seven times more likely to develop diabetes.

PCOS and Hormone Imbalance

Hormone imbalance in women suffering from PCOS include:

  • Raised levels of testosterone
  • Raised levels of luteinising hormone (LH) – a hormone that stimulates ovulation, but increased levels in some women with PCOS may have abnormal effect on the ovaries.
  • Raised levels of prolactin – a hormone that stimulates the milk production in pregnancy
  • Low levels of sex hormone binding globulin (SHBG) – a hormone that helps reduce the effect of testosterone.


Having PCOS can increase the patient’s chances of developing other health problems later in life. Complications include type 2 diabetes mellitus and consequent cardiovascular complications, depression and mood swings, as well as high blood pressure and high cholesterol, which can lead to heart disease and stroke.

The oligomenorrhoea and amenorrhoea increase the risk for endometrial hyperplasia and endometrial cancer in untreated cases. The risk of developing gestational diabetes in pregnant women with PCOS may be more than double, and there is a higher risk of pre-term birth and pre-eclampsia.

Evidence suggests that maternal PCOS was associated with increased hospitalizations for their offspring, including disease of the nervous system, metabolic disorder, and asthma.
