Testosterone deficiency symptoms include low libido, weight gain, anxiety, depression, mood swings, memory loss, sugar cravings and a “beer belly” appearance from weight gain. This usually starts in the mid- to late-30's, but certain medications, illness, and genetics can cause it to begin sooner.
During the early stage of estrogen deficiency, many women experience hot flashes and insomnia right before and during their period. Premenstrual syndrome (PMS) gets worse, and they may have migraines for the first time in their lives.
The mid-stage of estrogen deficiency sees hot flashes during random times throughout month (not just during periods), worsening PMS (just when they thought it couldn’t possibly get any worse), insomnia, forgetfulness and night sweats.
Late stage is usually marked by irregularity in menstrual cycles, and worsening symptoms overall. Women might go several months without getting a period, but suddenly they return, often becoming heavier, more frequent and longer lasting.
