Yes, it's quite common and generally considered normal to feel nauseous or even throw up on your period due to hormonal changes, especially rising prostaglandins, which cause uterine contractions but can also affect the gut, leading to cramps, headaches, diarrhea, and vomiting. These symptoms are often part of PMS, PMDD (severe PMS), or dysmenorrhea (painful periods) and usually subside within a couple of days, but if severe or persistent, it's best to see a doctor.
Hormones are usually the cause
For most women who experience nausea during or before their periods, it's just a normal part of pre-menstrual syndrome (PMS). A hormone called prostaglandin circulates around your body during your time of the month. It can cause nausea, vomiting, diarrhea and headaches.
Excessive cramping and vomiting could be a sign of an abnormal period. Heavy menstrual bleeding and prolonged menstrual cycles could also signify that you're dealing with this condition. Other examples of abnormal periods include: Periods that are less than three weeks apart or more than five weeks apart.
The problem is that prostaglandins are pretty potent and sometimes they get in the blood stream and go everywhere. Prostaglandins cause everything from cramps to muscle aches to nausea, diarrhea and (if you're really ``lucky'') vomiting.
Some of the most common period nausea remedies include consuming ginger tea, peppermint tea or fennel. You can also try acupressure and controlled breathing. Do consult the doctor before trying any home remedy.
Many girls throw up — or feel like they might throw up — just before or during their periods. Hormone changes are probably the cause, and these feelings usually go away in a day or two.
The blood is a healthy red colour
Menstrual blood that is a crimson red colour without the presence of clots or mucus occurs when there is adequate blood flow within the uterus. Dark, purple or brown blood and the presence of clots indicates poor uterine circulation.
Practical Tips to Manage Period Nausea and Vomiting
Period pain red flags include pain so severe it stops you from daily activities (work, school), doesn't improve with OTC meds (ibuprofen, Panadol), involves very heavy bleeding (soak pad/tampon hourly), or comes with new symptoms like painful sex, fatigue, digestive issues, or fever, signaling potential conditions like endometriosis, fibroids, or adenomyosis needing medical attention.
You might observe that as you age, your period pain can change. For some, period pain is common in the early years after their first period but tends to improve with time. However, for others, it's like period pain getting worse with age, especially as they reach their 30s and 40s.
Your periods become irregular after having been regular. You bleed for more than seven days. You bleed more heavily than usual or soak through more than one pad or tampon every hour or two. Your periods are less than 21 days or more than 35 days apart.
Continue counting each day of your cycle until your next cycle starts. On days 1-7, you're not considered to be fertile and can have unprotected sex, though you may have menstrual bleeding on those days. On days 8-19, you're considered to be fertile. Avoid unprotected sex or abstain from sex to avoid pregnancy.
But for some, the pain and cramping are so severe that it impacts their ability to function normally. Limited research suggests that period pain can be as painful as a heart attack. Menstruation or periods are the monthly vaginal bleeding that occurs as a person's body sheds the lining of the uterus.
Endometriosis can also cause gastrointestinal symptoms, such as nausea, vomiting, bloating, abdominal pain, and changes in bowel habits. Nausea is a “sick” feeling in the stomach or belly, like you are going to vomit. Many people report nausea as a symptom of their endometriosis, especially during their period.
During menstruation, you should avoid heavy/intense exercise, excessive caffeine, alcohol, salty/sugary foods, and tight clothing, as these can worsen cramps, bloating, and mood swings; also, practice good hygiene by changing menstrual products frequently (every 3-4 hours for tampons) to prevent infection and avoid strenuous activities if you feel fatigued or in pain.
Choose a pillow that supports your head and keeps it aligned with your spine - it should be the same thickness as the distance between your neck and shoulder. Sleeping on your side may also reduce the chances of waking with back pain, if you sleep with a thin pillow or blanket between your knees to even out your hips.
EARLY ENDOMETRIOSIS SYMPTOMS
Period cramps can be painful but are a normal part of the menstrual cycle. On the other hand, labor contractions in a pregnant woman occur when the uterus tightens to help push a baby out during childbirth. They are usually stronger and more regular than period cramps.
They are a sign that the prostaglandins in your body are working on your uterus muscles. These hormone-like substances make the womb muscles contract and relax which is why your period cramps come in waves. The contractions mean that the lining of your uterus stops receiving oxygen.
More than half of people who menstruate experience some level of pain during their menstrual cycle. Period cramps may be caused by recent lifestyle changes like sleep problems, stress, starting or stopping a new medication, or eating habits.
Yes—period diarrhea is a normal symptom for many women. Diarrhea during menstruation is a common phenomenon that occurs due to the same hormonal changes that cause your uterus to contract and shed its lining each month².
Heavy bleeding is not normal and may need treatment if: You have to change your tampon or pad more than once every 1 to 2 hours. Your period lasts more than 7 days. You or a family member have a problem with blood clotting.
The hormone changes can cause symptoms such as:
A normal menstrual cycle can last between 21 and 35 days. You can expect to bleed between three and seven days each time you get your period. Contact your healthcare provider if you have questions or concerns about your menstrual cycle.
