What's to Blame?
Judith Reichman, M.D., author of I'm Not in the Mood: What Every Woman Should Know about Improving Her Libido, lists seven possible libido killers in her book. Psychological issues, relationship difficulties, and medical and hormonal problems are major contributors, and it's realistic to expect sexual desire to wax and wane depending on physical and emotional health, mood, relationship dynamics and personal need. One of the most common complaints is too much stress.
Women and their health practitioners can check many areas while looking for a cause: is low libido a function of aging, too much exercise or too little, hormonal imbalances including low thyroid, depression, stress etc? Many common prescription medications, including antidepressants, blood pressure drugs, and even birth control pills can affect sexual drive as well. Check with your doctor about replacing problem drugs with substitutes, or changing dosages until the problem diminishes.
