While most of the hormonal changes are due to the decrease in estrogen,1 the progesterone level also decreases over time. That said, the decrease is more like a rollercoaster, as both levels rise and fall during perimenopause.3
Symptoms can be similar to PMS symptoms.2 On top of that, a decrease in estrogen can lead to bone thinning or changes in cholesterol levels. This is one of the reasons why regular check-ups with your doctor are encouraged.1
On the flip side, hot flashes or night sweats are linked to lower estrogen levels. What’s more, the up and down of the hormones can happen at the same time as a menstrual cycle.2
If your symptoms interfere with your health and well-being, or if you’re concerned about anything, speak to your doctor who may recommend hormone therapy, or other treatment, to help you transition smoothly through this beautiful season of your life.
