Nausea is a possible symptom both before and during menopause. It can occur as a result of decreased hormone levels, hot flashes, or hormone replacement therapy (HRT). Read on to learn more about why it happens, as well as ways you can treat it.

Some women report nausea before and during menopause.

While there’s no single cause of nausea, it’s possibly linked to hormone changes, other menopausal symptoms, and certain treatments. It’s important to note that symptoms vary greatly between women.

If you’re experiencing nausea on a regular basis and you are either in perimenopause or menopause, keep reading to learn more about the possible causes. Then, you can discuss further with a healthcare provider.

Nausea can be a symptom of menopause in some, but not all women. Possible causes include a natural drop in hormone levels, hot flashes, or side effects from hormone replacement therapy (HRT).

Decreased hormone levels

Menopause itself occurs as a result of a drop in female hormones called estrogen and progesterone. These hormones are normally produced in your ovaries and help regulate your periods.

Your ovaries can decrease the amount of these hormones anywhere between the ages of 45 to 55. The average length of the menopausal transition is 7 years, but it can last up to 14 years.

Hormone changes alone may be one cause of nausea during menopause. If you ever noticed nausea before your menstrual cycles, this was likely due to a natural drop in estrogen.

Hot flashes

Hot flashes are sensations that can come and go throughout the day, and are characterized by waves of warmth in your upper body, particularly your head and chest areas. Your skin may also turn red and blotchy.

Sometimes, hot flashes can make you feel nauseous.

Hormone replacement therapy (HRT)

HRT consists of laboratory-made estrogen and progestin. It may help alleviate symptoms during early menopause. Nausea is a known side effect of HRT when it is administered orally.

There are also serious side effects associated with this treatment when given long-term and in high doses. Some of these risks include blood clots and stroke, depending on how HRT is administered.

Treatment for nausea from menopause may involve a combination of lifestyle or dietary changes, along with prescription medications to help address the underlying causes.

Dietary changes

There are some foods and beverages that can make nausea and hot flashes worse. You may want to avoid or decrease your consumption of the following:

  • alcohol
  • spicy foods
  • caffeinated drinks, such as coffee and tea

You may also ask your doctor whether phytoestrogen-rich foods may help provide relief of your menopause symptoms.

Some women may find relief from naturally occurring low levels of estrogen in plant foods such as soy. However, more research needs to be done.

Herbal estrogen products have not been found to be effective or safe.

Alleviating hot flashes with lifestyle changes

If your nausea is related to hot flashes, you may find relief by addressing this underlying cause directly. While you may not be able to avoid hot flashes entirely, the following methods may help reduce their effects on your body:

  • avoid any known triggers, such as spicy foods and caffeinated drinks
  • stay in an air conditioned room whenever it’s hot and humid outdoors
  • drink plenty of water, especially when you start feeling a hot flash begin
  • dress in layers, preferably of breathable cotton or other natural fabrics
  • make sure your room is cool at night
  • keep cool compresses or portable fans handy when traveling outside your home
  • reduce stress and engage in relaxing activities as much as possible
  • try to exercise every day, and do so outdoors when the weather is cool
  • if you smoke, consider trying to stop

Prescription medications

If your symptoms don’t improve with lifestyle changes after three months, your doctor might recommend medications. These may be helpful if you experience nausea as a symptom related to other symptoms of menopause. Possible prescription treatments include:

  • HRT. While HRT may cause nausea and other side effects in some people, it may help treat menopause symptoms overall in others. Talk with your doctor about the risks versus benefits of HRT, as this treatment isn’t right for everyone. HRT may increase your risk for:
    • blood clots
    • stroke
    • breast cancer
  • Oral contraceptives. Low-dose birth control pills may help supply the right amount of female hormones to help offset menopause symptoms that could be causing nausea.
  • Selective serotonin reuptake inhibitors (SSRIs). When prescribed in low doses, SSRIs may help alleviate hot flashes and accompanying symptoms. These antidepressants may also help treat mood disorders and help you sleep better at night. Unfortunately, nausea is one possible side effect of SSRIs, so be sure to report any new symptoms to your doctor while taking these medications.

If you’re concerned about menopause-related nausea, it’s important to talk with a healthcare professional. This is especially the case if your nausea is chronic throughout the day, or if it’s severe enough to interfere with your regular activities.

Depending on your situation, your doctor may recommend treatments or lifestyle changes that may help you find nausea relief.

Nausea is a possible symptom of menopause that may be caused by changes in your hormones. It may also be a side effect of hot flashes or HRT. Not everyone will experience nausea while going through menopause.

If you find that your nausea is frequent or severe enough to impact your daily life, talk with a healthcare professional for treatment options. Lifestyle changes may be attempted before trying medications.
