17963 Primary Ovarian Insufficiency

Overview

Primary ovarian insufficiency (POI) is a condition where a woman's ovaries stop working normally before age 40. The ovaries produce eggs and hormones like estrogen. When they stop working early, it can cause irregular periods, low hormone levels, and trouble getting pregnant.

Primary ovarian insufficiency is not very common. It affects about 1 in 100 women under the age of 40.

It can affect anyone with ovaries, even teenagers, but it is most often diagnosed in women between ages 30 and 40.

Symptoms

Common symptoms

• Irregular periods, missed periods, or periods that stop altogether
• Hot flashes or night sweats
• Vaginal dryness or discomfort during sex
• Difficulty getting pregnant
• Low mood, irritability, or anxiety
• Trouble sleeping
• Low energy or fatigue

Symptoms in children

• In children and teens, POI is rare, but it may cause delayed puberty.
• A girl may not develop breasts or begin menstruation when expected.
• Few or no periods after puberty may be a sign.

Symptoms in older adults

• In women over 45, similar symptoms are usually a normal part of menopause, so POI is not diagnosed.
• POI is defined as ovarian failure before age 40, so it is not typically considered in older adults.

Causes

Main causes

• The cause is often unknown, especially when it happens on its own.
• Autoimmune disorders, where the body's immune system attacks the ovaries by mistake.
• Genetic conditions, such as Turner syndrome or Fragile X syndrome.
• Cancer treatments like chemotherapy or radiation that damage the ovaries.
• Surgery that removes the ovaries.

Risk factors

• A family history of primary ovarian insufficiency
• Autoimmune diseases, such as thyroid disease or Addison's disease
• Certain genetic conditions
• Past treatment with chemotherapy or radiation
• Being a carrier of the Fragile X premutation

When to see a doctor

See a doctor urgently if:

• If you are having very heavy bleeding or severe pelvic pain, get care the same day.
• If you are feeling severe anxiety, depression, or having harmful thoughts, get help immediately.

Book a routine appointment if:

• If you have missed periods for three months or more and you are under 40, see a doctor.
• If you have hot flashes, night sweats, or vaginal dryness before age 40.
• If you are having trouble getting pregnant, talk to your doctor about fertility concerns.

Diagnosis

A doctor will ask about your symptoms, your medical history, and any family history. They will also do a physical exam and order blood tests to check your hormone levels.

Tests that may be done

• Blood tests to measure follicle-stimulating hormone (FSH) and estradiol, to see how the ovaries are working.
• A blood test for anti-Müllerian hormone (AMH), which helps estimate the number of eggs remaining.
• Chromosome testing (karyotype) to look for genetic causes.
• Possible other scans or tests if the doctor wants to rule out other conditions.

What to expect at your appointment

If your periods are irregular and your FSH levels are high on more than one test, a doctor may diagnose POI. You may be referred to a specialist who focuses on hormones or female health.

Treatment

Treatment focuses on replacing the hormones your body is missing, managing symptoms, and protecting your bone and heart health. It also helps address emotional and fertility concerns.

Self-care at home

• Keep track of your symptoms and periods to discuss with your doctor.
• Manage stress with relaxation, mindfulness, or talking to someone you trust.
• Quit smoking and limit alcohol, as these can worsen bone and heart risks.
• Build a support network of friends, family, or support groups.

Medical treatments

Hormone replacement therapy (HRT) is often recommended to replace estrogen and progesterone. This can be given as pills, patches, gels, or vaginal creams. Some women may use the combined oral contraceptive pill as a way to manage symptoms. Your doctor will help decide what is safest for you, based on your age, health, and preferences. Do not start any hormone treatment without discussing it with your healthcare provider.

When is surgery considered?

Surgery is not a usual treatment for POI. In very rare cases, a doctor may suggest surgery if there is a suspicious mass on the ovary or if the diagnosis is unclear, but this is not common.

Living with this condition

Living with POI means paying attention to your body and staying in close contact with your healthcare team. You may need regular checkups to monitor your bone density, blood pressure, and cholesterol. It is important to follow your treatment plan and ask questions whenever you are unsure.

Lifestyle tips

• Stay active with weight-bearing exercises like walking, jogging, or dancing to keep bones strong.
• Eat a balanced diet rich in calcium and vitamin D.
• Keep a healthy weight and avoid extreme dieting.
• Limit stress and make time for activities you enjoy.
• Consider counseling or a support group if you are finding it hard to cope.

Diet and exercise

A healthy diet with enough calcium and vitamin D can help protect your bones. Good sources include dairy products, leafy greens, and fortified foods. Regular weight-bearing exercise, like walking or lifting light weights, also helps keep bones strong. Eat plenty of fruits, vegetables, and whole grains for heart health.

Mental health and emotional wellbeing

A diagnosis of POI can bring up many emotions, including sadness, anger, or grief over lost fertility. These feelings are normal. It is important to talk about them with a counselor, therapist, or a trusted person in your life. If you are feeling overwhelmed, please seek professional support.

Prevention

Primary ovarian insufficiency cannot be prevented in most cases. If it is caused by cancer treatment, there are some options such as egg or tissue freezing before treatment, but these must be discussed with a doctor beforehand.

Vaccines

There is no vaccine to prevent POI. However, staying up to date with routine vaccinations can help reduce the risk of infections that may affect overall health.

Screening programmes

There is no routine screening for POI in the general population. If you have a family history of POI or a genetic condition linked to it, your doctor may offer testing to check how your ovaries are working.

Complications

If left untreated

• Weaker bones (osteoporosis) because of low estrogen levels
• Higher risk of heart disease
• Difficulty getting pregnant or infertility
• Vaginal dryness and discomfort
• Significant emotional distress, including depression or anxiety

Long-term outlook

With proper medical care and support, most of these risks can be reduced. Many women with POI lead healthy and joyful lives. Fertility can be challenging, but there are options to explore with a fertility specialist. You are not defined by this condition, and you do not have to face it alone.
