Weight fluctuations during the menstrual cycle are a common experience for many individuals, and they can be attributed to several physiological changes that occur in the body. It is not unusual for women to notice an increase in weight, often ranging from 1 to 5 pounds, in the days leading up to and during their menstrual period. This weight gain is typically due to a combination of factors, including hormonal changes, water retention, and changes in appetite.

During the menstrual cycle, particularly in the luteal phase (the time between ovulation and the start of menstruation), the body experiences an increase in hormones such as progesterone. This hormone can lead to water retention, which is one of the primary reasons for temporary weight gain. Additionally, some women may experience cravings for certain foods, often high in carbohydrates or sugars, which can lead to increased calorie intake, although you mentioned that your eating habits have not changed significantly.

As for when you can expect to return to your baseline weight, this typically occurs shortly after your menstrual period begins. Once menstruation starts, the hormonal levels begin to stabilize, and the body tends to shed the excess water weight. Most women find that their weight returns to normal within a few days after their period starts.

Regarding your experience of severe menstrual pain, also known as dysmenorrhea, it is important to note that this can vary significantly from person to person. Symptoms can range from mild discomfort to severe pain that interferes with daily activities. The pain is often caused by the release of prostaglandins, which are chemicals that trigger uterine contractions. In some cases, high levels of prostaglandins can lead to more intense contractions, resulting in increased pain.
The symptoms you describe, such as cold sweats and vomiting during your menstrual period, may indicate that your pain is more severe than typical dysmenorrhea. This could be a sign of a condition known as endometriosis, where tissue similar to the lining of the uterus grows outside the uterus, or it could be related to fibroids or other pelvic conditions. It is essential to consult with a healthcare provider if you experience debilitating pain, as they can perform a thorough evaluation and recommend appropriate treatment options.

In summary, weight gain during your menstrual cycle is generally normal and is often temporary due to hormonal fluctuations and water retention. You can expect to return to your usual weight shortly after your period begins. However, if you are experiencing severe menstrual pain accompanied by other symptoms such as cold sweats and vomiting, it is advisable to seek medical attention to rule out any underlying conditions and to discuss potential treatment options for managing your symptoms effectively.
