Perimenopause symptoms & why they can come and go

It can be really frustrating when a symptom finally settles down, only for it to come back again months or even years later. Your hot flushes almost went and now they're back, or they're worse. It can happen with anxiety or fatigue, or brain fog.

So, what's going on? If you're in perimenopause and you're still having periods, or they're light,  scrappy or petering out, your hormones may still be really erratic. In a perfect world, your hormones would wane really gradually and gracefully and give you lots of time to adjust. But there can be really sudden drops or peaks in hormones that can cause really changeable symptoms.

Perimenopause can last for a few months or decades, so there's always a possibility a symptom can come or go, especially if you've a lot on, or run down, or sleep deprived, or stressed. These factors can all ramp up the risk of you experiencing uncomfortable symptoms.

If something feels really wrong, or you're in menopause already, and you haven't had a period for a few years, and something like hot flushes has appeared out of nowhere, it's sensible to get checked out.

Temperature fluctuations can happen when the thyroid gland is wobbling. Medications can have side effects which cause similar symptoms, and so can can nutritional deficiencies like low Vitamin D. These are all worth getting check out by your GP.

What to do to help yourself

Regardless of your circumstances, supporting the nervous system with quality rest and sleep is going to help with energy and moods, and keep you on an even keel so that erratic hormones are not quite so destabilising.

Things like Passiflora, magnesium, valerian and hops can be helpful if you need something calming. You can get these in supportive supplements and sprays.
