Diarrhea during period

Menstruation (or period) is directed by the hormonal changes in the female reproductive system. Some women experience short and lighter periods, while others have long and heavier cycles. The flow may also change over a period of time. Bloating, cramps, mood swings, fatigue, etc. are some of the symptoms you may experience before and during your period. The cycle may also affect your gastrointestinal tract (GI tract) resulting in diarrhea and abdominal pain. Though painful and unpleasant, these changes during your monthly cycle are completely normal.

Some women have moderate digestive discomfort due to their menstrual cycle, while others face serious problems. Unfortunately, you do not have control over your hormones. When the hormone levels settle down after your period, your bowel movement also returns to normal. Irrespective of the symptoms, you can take measures to treat them or probably prevent them entirely.

What causes diarrhea before period?

Premenstrual syndrome (PMS) is a group of symptoms that many women experience a few days before their period. It affects your emotions, behavior, and physical health. Changes in some hormones can cause irritability, back pain, mood swings, and anxiety. Most PMS symptoms develop one to two weeks before your cycle.

The lining of your uterus starts to break down a few days before your period and releases the hormones called prostaglandin. These hormones when released in excess affect your digestive system. Gastrointestinal symptoms like nausea, bloating, and diarrhea may also occur a few days before your period.

What causes diarrhea during period?

During the period, as the uterus sheds its lining, it contracts. Prostaglandin hormones trigger the phenomenon of uterus contraction. These hormones also regulate the contraction and relaxation of the digestive tract muscles. This often results in diarrhea.

Irregular bowel movements can happen when these hormones relax smooth muscle tissues as your period begins. It also decreases the rate of food absorption, which might be another reason for frequent bathroom visits. In a nutshell, the imbalance in prostaglandin causes you to poop often and experience diarrhea.

Can diarrhea continue after period ends?

If you experience symptoms after your period, it’s not uncommon. You may feel cramps in your lower abdomen and back. Your thighs and hips may ache as well. Nausea and light-headedness can be followed by cramping and aching. You may also experience stomach pain, constipation, or diarrhea even after your period ends.

Post-period symptoms aren’t typically serious. However, it is imperative to monitor them, especially if they last longer.

Can menstrual cramps cause diarrhea?

Menstrual cramps are pains that you experience in your lower abdomen. They can arise before your cycle starts and can last for 2 to 3 days. Your cramps may be aching or throbbing, or it can be sharp or dull. Symptoms may vary from mild discomfort to extreme pain.

All the symptoms of menstrual discomfort are related to hormonal changes. Diarrhea during period is often linked to menstrual cramps. The chemicals released during this time cause uterus and intestine to contract, thus affecting your digestive system.

Menstrual cramps can cause diarrhea

Why is there blood in my stool during period?

During menstruation, the production of prostaglandin increases. This results in uterus contraction. The excess release of these hormones leads to pain and menstrual cramps.

When prostaglandin levels are high, they can reach your bloodstream and then travel to other parts of your body, including the bowels. This is why you see blood in your stool during period.

PMS, eating habits and changes in hormone levels are the reason for your smelly poop during your cycle. Your period poop differs from your regular poop. Usually, it is more frequent and loose. Menstrual blood has a smell too, and it may contribute to foul poop smell.

What are other digestive issues during period?

Period can cause havoc on your digestive system. You may experience other digestive issues too, both before and during your menstrual cycle. Some common ones are bloating, gas, constipation, and frequent bowel movements. With every cycle, these symptoms can vary. You may have diarrhea for a few cycles, while you may feel constipated over the next few. In most cases, the cause is the same hormone – prostaglandin. However, alteration in your diet may also play a role in these changes.

Some women experience diarrhea, while others face constipation. At times, the high levels of progesterone cause the muscle of your digestive tract to relax. This results in gas, bloating, and constipation. When this happens, your digestive tract is so comfortable that it does not contract and flush out the waste as it would usually, leaving stuff to stagnate.

Women who are more sensitive and experience depression or anxiety, are more likely to experience several GI symptoms. Being in good mental health can help during periods.

Is it normal to vomit during period?

Experiencing nausea during your period is fairly normal. Usually, it’s triggered by hormonal and chemical changes that take place during the menstrual cycle. Such symptoms are common and are not a cause for concern.

Excess prostaglandin during periods can cause nausea and vomiting. Apart from triggering pain and uneasiness, increased levels of prostaglandin do not pose any health risks.

If your nausea is accompanied by severe pain or fever, there might be an underlying condition. It is advisable to visit your doctor in that case.
