We welcome your questions and comments about MIA products.
The volume of menstrual discharge may vary from cycle to cycle. If you have noticed that your period has become lighter than usual, there may be an underlying reason other than illness. Your period is affected by many factors, so health problems may not be the only reason.
These changes in your routine may make your discharge become lighter:
1. You’ve lost or gained weight
Changes in your weight can mess with your menstrual cycle, making your periods a lot shorter or lighter. Body fat (also known as adipose tissue) actually produces a type of estrogen. The more estrogen there is in your body, the more likely it is that the lining of your uterus will build up during the first half of your cycle and shed during your period. The thicker the lining, the heavier your menstrual flow. As you lose weight, the amount of estrogen in your body may decrease, so your lining may become thinner and your flow lighter.
2. You’re stressed out
Routine annoyances may not affect your cycle in this way, but if you’re experiencing situations which are particularly stressful, like grieving, quitting a job, or depression, your hormones will most likely get thrown out of whack.
Sport has many positive impacts on your body. Regular, moderate exercise can lead to subtle changes in your hormone levels, as it puts some stress on your body. As a result of this physiologic stress, the hormones that regulate your menstrual cycle can be disrupted. Keep in mind that weight change as a result of exercise can also contribute to hormonal fluctuations.
4. Hormonal birth control
If you have recently started to use hormonal contraception, like the pill, IUD, the patch, or the ring, and your periods have become lighter, it’s OK. It is normal to have light cycles, to completely skip cycles, or have small amounts of dark or light blood after you start using a hormonal birth control.
If you work rotating shifts for a long time, it may affect your menstrual cycle. This happens due to the disruption of circadian rhythms, which directly influence your menstrual cycle. Shifts in the circadian rhythms, either through sleep disturbances or altered melatonin production, may affect the regulation of the reproductive hormones that control the menstrual cycle.
According to a study, women with 20+ months of rotating shift work were more likely to have irregular cycles and an altered cycle length of less than 21 days or more than 40 days.
If your periods have become lighter without any significant lifestyle changes, see your ob-gyn to figure out the reason. Monitor your cycle with the MIA app to spot any possible alterations in your symptoms.
