When women enter their late 30’s or early 40’s they begin to experience hormonal changes that are the start of perimenopause. Perimenopause can last as many as 10 years, ending in menopause, which is the end of a woman’s reproductive years. The problem for teens is that during this transition, mom will become, at times, emotionally unpredictable and irrational. How can teenagers determine if their mom is in perimenopause? -Is she unusually moody, irritable or explosive? -Are her reactions to minor events out of proportion? -Is she weepy and emotional? -Does she seem irrational…maybe even surprised at herself at times?-Is she complaining about not sleeping well, being forgetful or tired? -Is she doing bizarre things such as putting her keys in the refrigerator or forgetting to turn off the stove? The important thing to remember is that even though mom may appear angry at you, it is not about you. Some women do not understand what is happening and most have trouble controlling the emotional highs and lows. Understanding perimenopause will help you find ways to cope with mom’s behavior…and maybe even help her through this difficult time.
