PCOS-Diät: Was man essen sollte, um Symptome zu managen

Was ist PCOS?

PCOS is a hormonal disorder that affects 1 in 10 women worldwide. If you have PCOS, you may have irregular or absent periods. This is because your ovaries do not release eggs as regularly as they should.

Dr Megan Lyons, Double Board Certified Doctor of Clinical Nutrition, The Lyon's Share Wellness, Dallas, USA explains that one of the hallmark symptoms of PCOS is the presence of multiple ovarian cysts, which gives the condition its name.

However, they are not actually cysts. They're painless, fluid-filled sacs (follicles) surrounding your ovaries that cause them to become enlarged. The abnormal hormone levels in PCOS can prevent some of these follicles from growing and maturing to release eggs. This contributes to irregular menstrual cycles and some cycles where eggs aren't released at all (anovulation).

Lyons says: "People with PCOS also have high levels of androgens. These are traditionally thought of as male hormones, but are present in both men and women at different levels. In women with PCOS, these androgens are higher than normal."

Alyssa Pacheco, Registered Dietitian, The PCOS Nutritionist Alyssa, Greater Boston, USA says that PCOS can present differently and cause a variety of symptoms.

Not everyone with polycystic ovaries will have PCOS and not everyone with PCOS has polycystic ovaries.

For diagnosis, you need any two of the following:

• Polycystic ovaries - usually seen on an ultrasound scan. An ovary might have more than 20 cysts.

• Signs of high androgen levels - for example high testosterone levels from blood tests or symptoms of high testosterone such as hirsutism or acne.

• No or infrequent periods.

Pacheco says that PCOS is linked to an increased chance of developing type 2 diabetes, heart disease, Fettleber, and endometrial cancer.

How can diet help with PCOS?

PCOS diet: what to eat to manage symptoms

Up to 70% of women with PCOS have Insulinresistenz. Insulin is a hormone your body makes to stabilise your blood sugar levels.

Lyons says that though PCOS is often categorised as a hormonal disorder, it is increasingly considered a metabolic condition because much can be done to manage it through food and lifestyle changes. One of the most effective strategies for managing PCOS is blood sugar stabilisation.

Pacheco explains that PCOS is also linked with chronische Entzündung.

"Insulin resistance and inflammation can each increase androgens - such as testosterone levels - which cause a lot of the typical PCOS symptoms," she says. "By including certain foods, in specific patterns, that maintain stable blood sugar levels and lower inflammation, you can see a decrease in PCOS symptoms."

Foods to eat with PCOS

To help stabilise blood sugar levels, it's important to focus on the types of foods that support blood sugar regulation and lower inflammation.

Lyons says that when your body is not constantly fighting inflammation, it has more resources available to regulate hormones effectively.

Both Lyons and Pacheco recommend the following foods to help ease PCOS symptoms.

Pacheco recommends pairing high-fibre carbohydrates with protein and healthy fats at meals for an optimal combination to keep blood sugar levels more stable.

Foods to avoid with PCOS

When modifying your diet to help manage PCOS symptoms, it's important to minimise foods that cause blood sugar spikes.

Lyons says these include refined carbohydrates and sugary foods such as bread, pasta, pastries, muffins, bagels and sugary drinks. She also recommends cutting back on trans fats, low-quality fats, inflammatory oils - such as processed and refined seed oils - and alcohol.

Pacheco agrees that these types of foods can worsen inflammation or insulin resistance if they're consumed frequently, or in high amounts.

What else can help with symptoms of PCOS?

According to Pacheco, while diet can certainly help PCOS symptoms, it's not the only thing you can focus on.

"Exercise, getting enough sleep, and stress management are all big factors when it comes to hormone health," she says.

Make time for exercise

Physical activity plays a crucial role in managing PCOS. A balanced exercise routine - incorporating strength training and moderate cardio - can significantly improve PCOS symptoms.

Lyons advises that while people with PCOS shouldn't overexert themselves with intense activities such as running marathons, a moderate amount of low-intensity cardio can also be beneficial.

She adds: "Strength training also helps with blood sugar regulation, reduces insulin resistance, and decreases inflammation."

Sleep well, stress less

In addition to exercise, sleep is another key element of PCOS symptom control.

"Lack of sleep can make insulin resistance worse. Likewise, long-term stress should be managed, as it can lead to cortisol dysregulation," says Lyons. "Cortisol is a hormone that affects both blood sugar and insulin levels - as well as androgens. So when cortisol levels are out of balance, it can make PCOS symptoms worse."

Nahrungsergänzungsmittel

Current UK guidance from the British Dietetic Association (BDA) advises that no supplements are necessary - or have a good evidence base - for their use in managing PCOS.

Effectively managing PCOS symptoms involves an integrated approach involving healthy dietary choices, regular exercise, quality sleep and stress management.

Lyon concludes: "By stabilising blood sugar and reducing insulin resistance, you can address the root causes of many PCOS symptoms. This can lead to improved hormone balance and overall wellbeing."
