What Symptoms Are Common During Perimenopause?

Perimenopause is the hormonal transition leading up to menopause, and it can begin earlier than many women expect. For some, symptoms appear in their late 30s or early 40s.

Because hormone levels fluctuate during this stage, symptoms can vary widely from person to person.

One of the most common symptoms is sleep disruption. Many women report difficulty falling asleep, frequent nighttime waking, or feeling unrefreshed in the morning. Hormonal changes affecting progesterone and estrogen influence the brain systems that regulate sleep.

Another frequent symptom is fatigue. Even women with healthy lifestyles may notice lower energy levels or slower recovery from exercise and stress.

Cognitive changes are also common. Many women describe brain fog, forgetfulness, or difficulty concentrating. These symptoms are thought to be related to how estrogen interacts with neurotransmitter systems in the brain.

Mood changes may occur as well. Hormonal fluctuations can influence neurotransmitters involved in emotional regulation, which may contribute to irritability, anxiety, or decreased stress tolerance.

Some women also notice changes in metabolism and body composition. Estrogen plays a role in regulating insulin sensitivity and fat distribution, which may explain increased abdominal fat during midlife.

Hot flashes and night sweats are widely recognized menopause symptoms, but they can also occur during perimenopause.
