Low carbing can help to balance your hormones more healthily, which can help to reduce the breast pain issues felt by some during menopause.
Breast pain - known medically as mastalgia - is usually caused by hormones in the woman's system. This is most clear when a woman gets pregnant. Through the actions of hormones, her breasts get larger and begin producing milk. It's no surprise that the monthly flush of hormones in her system can cause her breasts and nipples to become tender and sore.
This can often get much worse during menopause, as the hormone swings become more extreme and the woman's body begins to adjust to life without a period. A doctor can help determine if medicine is needed to help a woman get through this period of adjustment.
Stress tends to make issues like this worse - to exacerbate any hormone fluctuations. One way to help reduce the effects of hormone swings is to reduce stress as much as possible.
Note that there are other issues - such as cysts - which can cause breast pain. If you have breast pain that does not seem to change with your hormone cycle - or if you have any breast pain that concerns you - always talk with a doctor.
In general, low carb diets help to smooth out the highs and lows in your blood sugar levels and stress levels. This then helps to reduce issues such as breast pain and irritability, meaning that your breast pain can very much reduce.
