PCOS symptoms with fever
Informed by recognized medical guidance
Overview
PCOS (polycystic ovary syndrome) is a common hormonal condition that affects how the ovaries work. It can cause irregular periods, excess body hair, and difficulty getting pregnant. Having PCOS does not cause fever. A fever usually means your body is fighting an infection or illness. If you have PCOS and develop a fever, it's important to find out what's causing it.
Key facts
- PCOS is not an illness that causes fever by itself.
- A fever with PCOS may signal an infection or another medical issue.
- Treating the cause of the fever is important, not just the fever itself.
PCOS is very common, affecting about 1 in 10 women and people with ovaries of childbearing age. But fever is not a typical symptom of PCOS.
PCOS affects people with ovaries, usually starting in their teens or early twenties. A fever can happen to anyone, but if you have PCOS, any new fever should be checked.
Symptoms
- Fever with sudden, severe abdominal pain
- Fever with confusion or fainting
- Fever with trouble breathing or chest pain
- Fever with vomiting that doesn't stop
- ⚠Fever over 38°C (100.4°F) that lasts more than 3 days
- ⚠Fever with pelvic pain or unusual vaginal discharge
- ⚠Fever with pain or burning when urinating
- ⚠Fever with heavy bleeding or pain during sex
Common symptoms
- Irregular or missed periods
- Excess facial or body hair
- Acne or oily skin
- Weight gain, especially around the belly
- Thinning hair on the head
- Difficulty getting pregnant
Causes
Main causes
- PCOS is caused by a combination of genetics and factors like insulin resistance, which affects how your body uses sugar.
- Fever in someone with PCOS is usually due to a separate infection, such as a urinary tract infection, pelvic infection, or a respiratory virus.
- Sometimes hormonal changes can affect your body's temperature regulation, but a true fever above 38°C is not directly caused by PCOS.
Risk factors
- Having PCOS may increase your risk of certain infections, like uterine infections, but this is not fully proven.
- Insulin resistance and obesity, which are common with PCOS, can make your immune system less effective.
- Irregular periods can lead to a higher chance of endometrial hyperplasia, but that doesn't cause fever.
When to see a doctor
See a doctor urgently if:
- If you have a fever with severe abdominal pain, fainting, confusion, or difficulty breathing, call your local emergency number right away.
- If you have a fever after a recent pelvic procedure or if you are pregnant with PCOS, seek urgent care.
Book a routine appointment if:
- If you have a mild fever that lasts more than 2 days, or any fever with pelvic pain, discharge, or burning during urination, see a healthcare provider within a day or two.
Diagnosis
To diagnose PCOS, a healthcare provider will ask about your symptoms, do a physical exam, and may order blood tests to check hormone levels. They may also do an ultrasound to look at your ovaries. If you have a fever, your provider will also look for the cause, such as testing your urine, blood, or doing a pelvic exam.
Tests that may be done
- Blood tests: to check hormone levels (androgen, estrogen, etc.) and signs of infection (white blood cell count).
- Pelvic ultrasound: to see if your ovaries have cysts or are enlarged.
- Urine test: to check for a urinary tract infection.
- Pelvic exam: to check for tenderness or discharge.
What to expect at your appointment
Your healthcare provider will explain what tests are needed. There is no single test for PCOS. The diagnosis is based on having at least two of these three: irregular periods, signs of high androgen levels, and polycystic ovaries on ultrasound. For fever, they will treat the underlying cause.
Treatment
There is no cure for PCOS, but symptoms can be managed with lifestyle changes and, if needed, medications to regulate your cycle and hormones. For fever, treatment depends on the cause. If it's an infection, you may need antibiotics or antiviral medicine. Never take antibiotics without a prescription.
Self-care at home
- Drink plenty of fluids to stay hydrated when you have a fever.
- Get plenty of rest.
- Use a cool cloth on your forehead or take a lukewarm bath to feel more comfortable.
- Monitor your temperature regularly and note any other symptoms.
Medical treatments
For PCOS management, healthcare providers may prescribe hormonal birth control to regulate periods, or other medications to help with insulin resistance or ovulation. Never start or change any medication without talking to your doctor. For fever, treat the underlying cause as directed by your provider. You can ask your pharmacist about options to reduce fever, but follow their advice.
When is surgery considered?
Surgery is rarely needed for PCOS. In some cases, a procedure called ovarian drilling may be offered to help with ovulation, but it's not for fever.
Living with this condition
Living with PCOS means managing your symptoms and staying aware of your overall health. If you develop a fever, treat it as you would any other infection and seek advice if it persists.
Lifestyle tips
- Stay physically active for at least 30 minutes most days.
- Eat balanced meals with plenty of vegetables, whole grains, and lean proteins.
- Keep a symptom diary to track your periods, pain, and any fever episodes.
Diet and exercise
A healthy diet and regular exercise can improve insulin resistance and help manage PCOS symptoms. Aim for a balanced plate at each meal, and include strength training twice a week.
Mental health and emotional wellbeing
Living with a chronic condition like PCOS can be stressful. Fever and frequent infections can add to that stress. It's normal to feel anxious or down. Talk to your healthcare team about your feelings.
Prevention
PCOS itself cannot be prevented, but you can reduce your risk of complications by staying active, eating well, and managing your weight. To prevent infections that could cause fever, practice good hygiene, stay hydrated, and get vaccinated as recommended.
Vaccines
Stay up to date on recommended vaccines, such as flu and COVID-19, to reduce your chance of viral fevers. Ask your pharmacist or healthcare provider about what's right for you.
Screening programmes
If you have PCOS, your healthcare provider may check your blood pressure, blood sugar, and cholesterol regularly. There is no routine screening for fever.
Complications
If left untreated
- Untreated infections in the pelvic area can spread and cause serious illness.
- Unmanaged PCOS can increase the risk of type 2 diabetes, high blood pressure, and endometrial cancer over time.
- Chronic inflammation may make infections more severe.
Long-term outlook
With the right care, most people with PCOS live a healthy and full life. Treating the cause of any fever promptly will help you recover quickly. PCOS symptoms can be managed, and there are many effective strategies to help you feel your best.
