menstrual periods. These are normal premenstrual
symptoms. But when they disrupt your daily life, they are called premenstrual
syndrome (PMS). PMS can affect your body, your mood, and how you act in the days leading up to your menstrual period.
Some women first get PMS in
their teens or 20s. Others don't get it until their 30s. The symptoms may get
worse in your late 30s and 40s, as you approach

Your doctor will want
you to keep a written record of your symptoms for 2 to 3 months. This is called a menstrual diary. It can help you track when your
symptoms start, how bad they are, and how long they last. Your doctor can use
this diary to help diagnose PMS.
A few lifestyle changes will

Talk to your doctor if these changes don't provide some relief from your symptoms after a few menstrual cycles. He or she can prescribe medicine for problems such as bloating or for more severe PMS symptoms. For example, selective serotonin reuptake inhibitors (SSRIs)

Premenstrual syndrome (PMS) and the more severe form,
premenstrual dysphoric disorder (PMDD), are linked to
normal changes in the
endocrine system. The endocrine system makes hormones that control the
menstrual cycle. The female endocrine system
is very complex. Medical experts don't fully understand why normal hormone changes
cause PMS in some women and not others.
The one direct cause
that is known to affect some women is genetic: Many women
with PMS have a close family member with a history of PMS.
Premenstrual symptoms occur between
ovulation and the start of menstrual bleeding. More than 150 symptoms have been linked to PMS. They may vary greatly from cycle to cycle and be worse during times
of increased stress.
Women who have severe premenstrual
mood swings, depression, irritability, or anxiety (with or without physical
symptoms) are said to have
premenstrual dysphoric disorder (PMDD). Symptoms
generally go away within the first 3 days of menstrual bleeding. This severe
type of PMS isn't common.
Some medical conditions may get worse between ovulation
and the first day of menstrual bleeding.
The conditions most affected include:
What seems like PMS can sometimes be caused by another
condition. It's important to know what is causing your symptoms so you can get the right treatment. The best way to learn if your symptoms are PMS is to keep a
menstrual diary(What is a PDF document?) for 2 or 3 months and then show it to your health professional.
Most women first get PMS in their mid-20s, but it becomes more common in women in their 30s. Women in their late 30s and early 40s may have

thyroid problems sometimes cause symptoms like those of PMS. So you may have a
thyroid-stimulating hormone (TSH) blood test to make
sure that your
thyroid gland is working properly.
It's important for your doctor to rule out other
conditions that cause symptoms like those of PMS, so it may take more than one visit to
diagnose your symptoms. Diagnosing PMS may be difficult if you have another condition that
gets worse during the last 2 weeks of your
There are ways to reduce your PMS symptoms and their impact on your life. But no single treatment works
for all women. You may have to try several to find the right choices for you.
The first step is to try some lifestyle changes, such as limiting caffeine and getting regular exercise. For more information, see Home Treatment.

You can't prevent
PMS. But there are things you can do
to reduce your chances of having severe symptoms.
The first step in learning to manage PMS is to keep a menstrual diary(What is a PDF document?). Write down what kind of symptoms you have, how severe they are, when you have your period, and when you ovulate. This can help you identify patterns in your cycle and plan ahead to better cope with the symptoms.
Next, use some self-care measures for PMS. They focus on practicing healthy habits, managing pain, and reducing stress. When you use these tips, it's best to:
If you have moderate to severe premenstrual symptoms even after you've tried home treatment and lifestyle changes, talk to your doctor
about using medicine. Be safe with medicines. Read and follow all instructions on the label.
