Why test oestrogen levels?

Oestrogen is one of the four sex hormones that drives key bodily functions, including the menstrual cycle; with abnormal levels causing a host of symptoms and long term conditions. It is very important that women understand how their 4 sex hormones are rising and falling during their monthly cycle as they intricately work together. Abnormal levels of oestrogen can be caused by a number of factors which can be identified with testing. Forth’s MyForm test uses proprietary AI technology to map your hormones during your cycle to give you a detailed view of how your hormones are fluctuating, with a detailed report of actions that can be taken to improve their levels.

What are the symptoms of low oestrogen?

The symptoms of low oestrogen include: hot flushes changes in mood decreased bone density fatigue sleep disorders sexual dysfunction The reduction in oestrogen at the time of menopause has also been linked to the development of osteoporosis in postmenopausal women. A natural fall in oestrogen in men can cause osteoporosis in elderly men as well.

What does oestrogen do in the menstrual cycle?

Oestrogen is one of the four sex hormones that rise and fall significantly during the menstrual cycle to regulate the release of an egg from the ovaries. During the Follicular Phase, a follicle in the ovary starts developing as it prepares to release an egg. This produces oestrogen, the main ovary response hormone during this phase, which peaks just before Ovulation. Oestrogen makes the lining of the uterus thicker and more receptive to a fertilised egg, and it can also increase libido which is your body’s way of driving reproduction.

How can I reduce my oestrogen levels?

Oestrogen is an essential sex steroid hormone in the body, but too much of it can cause irregular periods and worsen your reproductive health. It is rare for high oestrogen to be caused by what your body is producing. Often medications such as hormonal contraceptives can lead to high levels of oestrogen, reducing libido as an example. In this case, you should speak to your GP about appropriate changes to your care plan. High oestrogen unrelated to medication can be caused by PCOS prior to menopause, and being overweight after menopause. In general, you should look out for: being overweight (body fat tissues secrete oestrogen) medications that raise oestrogen stress increases cortisol, which can reduce progesterone levels. This allows oestrogen levels to go unchecked liver health issues that can prevent the effective breakdown of oestrogen, allowing it to accumulate drinking too much alcohol can reduce your body’s ability to breakdown oestrogen potentially having polycystic ovary syndrome (PCOS), which can be checked with our PCOS test

How can I increase my oestrogen levels?

Oestrogen levels can potentially be boosted naturally through the following methods: Food – eating more sesame seeds, soybeans, and flax seeds Supplements – taking Boron, DHEA, B vitamins, and vitamin D Herbal supplements – taking chasteberry, red clover, dong quai, and black cohosh If you are experiencing the symptoms of perimenopause, it may be advisable to discuss HRT with your GP as studies show that starting this treatment option early can reduce the risk of long term health conditions.

Oestrogen is a sex steroid hormone that has 3 forms in women: oestrodiol, oestrone, and oestriol. Oestrodiol is the strongest and main form of oestrogen in the body. Oestrogen will be at its highest levels during reproductive years and falls significantly during perimenopause. Oestrogen is produced mostly in the ovaries of women of reproductive age, with adrenal glands and body fat tissue also secreting oestrogen. It is one of the four sex hormones that rise and fall during the menstrual cycle to regulate the release of an egg from the ovaries. Oestrogen is responsible for feminine characteristics, but it is a hormone also found in men.

"Oestrogen is the main ovarian hormone, this test offers a snapshot picture of your oestrogen levels. Although useful to monitor fertility, menopause, or hormonal imbalances it should be used as part of a wider panel to help understand your whole hormone network."

We’re changing people’s lives

I really like Forth and you probably saved my life because your lab discovered my critically low cortisol which was subsequently diagnosed as adrenal insufficiency by a hospital endocrinologist.

Maria

I find Forth professional and forward-thinking with a bigger range of tests than more traditional healthcare providers in the UK. I think it is closer to what you can get from US providers.

Richard C

I wanted to get more information about my own health instead of using the NHS who just test for a specific reason. I also wanted better historical data to view changes over time as the NHS systems aren’t very good for that.

James W

Finding out what is going on inside your body is key, especially now that the NHS is in crisis. If we can take control of our wellness (and flag up potential problems early) that has got to be a good thing.

Vannesa C

I am very satisfied with your excellent service and I have recommended you to all my friends who are also very interested in your products.
