2 The symptoms of PCOS are caused by imbalances in hormones and insulin resistance. What is insulin? Insulin is a hormone. It helps the body to use sugar as energy. What is insulin resistance? Insulin resistance happens when the body does not respond to insulin properly. When this happens, the body produces more insulin to compensate. This causes the level of insulin in the blood to become higher than normal. A high amount of insulin in the blood may make it a little harder to lose weight (however, weight loss is not impossible). It also increases the level of testosterone in the blood. Testosterone is a hormone which naturally occurs in small amounts in all women. But in people with PCOS, testosterone levels are higher than normal due to insulin resistance. High levels of testosterone in the blood cause symptoms of excess hair, irregular periods, acne, and difficulty in conceiving. Insulin resistance becomes worse when we gain weight, or are over weight. Body not responding to insulin properly Weight gain May encourage fat storage and increase cravings for sweet foods Insulin resistance can be made worse by: l Poor diet l Lack of exercise l Smoking l Carrying excess weight around your waist weight = insulin resistance = PCOS symptoms weight = insulin resistance = PCOS symptoms REMEMBER: Just losing 5% of your weight can improve symptoms of PCOS Body produces more insulin to compensate Higher levels of insulin in the blood More testosterone produced Symptoms: Excess hair, acne, irregular periods, difficulty in conceiving Insulin resistance can be improved by: l Losing weight l Regular exercise l Eating a healthy diet and following a regular meal pattern l Choosing lower GI foods where possible (see page 6) 1 2

3 Other health problems Having PCOS means that you are at higher risk of developing heart disease, diabetes and some forms of cancer. Losing weight and making simple changes to your lifestyle can reduce your risk. So what can I do to lose weight, manage my PCOS symptoms, and reduce my risk of developing other health problems? l Eat regularly - never skip meals. Aim to have 3 regular meals per day with low kcal snacks in between if required l Aim to have a small amount of starchy foods such as bread, potatoes, pasta, rice, breakfast cereals at every meal. Try to opt for low GI options where possible (see page 6) l Aim to eat 5 portions of fruit and vegetables per day l Drink plenty of low kcal fluids l Ensure portion sizes are appropriate l Limit high fat high sugar food and drink l Keep alcohol intake to a minimum as it is high in calories Don t forget exercise! There is a wealth of evidence to support the benefits of physical activity in people with PCOS including: helping to reduce insulin resistance, helping achieve weight loss, improving mood, protecting against developing diabetes and heart disease. If you don t do much exercise currently, remember - any exercise which is more than you would normally do is a great start. Low Glycaemic index (GI) Foods l GI is a measure of how quickly starchy carbohydrate (i.e. bread, potatoes, pasta, rice, grains, noodles, breakfast cereal) is broken down into sugar and absorbed by the body l A starchy carbohydrate that is classed as low GI means it is broken down into sugar slowly. This means your blood sugar levels are less likely to rise and fall sharply l Low GI does not mean that the food is low in calories or fat l Adding protein or fat to a carbohydrate will slow down its absorption e.g. adding tuna or beans to a baked potato (high GI) will result in a medium GI meal l All types of beans, lentils, chickpeas and pulses have a low GI l It is not necessary to limit any fruit and vegetables as long as you control your portion size l Limit sugary food and drink such as sweets, cake, sweet biscuits, fizzy drinks, chocolate etc l Pure fruit juices are high in natural sugar and are therefore high in GI. Drink no more than 1x small glass per day l Don t add sugar to hot drinks or food. Opt for sweeteners instead l Alcohol can increase blood sugar levels if drunk in large quantities. Sugary alcoholic drinks such as cocktails, or drinks with sugary mixers (fizzy pop, fruit juice etc) will increase blood sugars even in small amounts 3 4
