Hello,
Disinterest in sex or loss of libido commonly occurs due to
depression,
anxiety, stress(physical & emotional), low self-esteem,
hormonal problems, chronic illness, relationship problems.
You are suggested to get clinically examined for hormonal imbalance, PCOS,
thyroid issues, anemia or any other pathological problems causing such discomforts.
Get detected, get treated at the earliest. Relationship problems may cause disinterest & loss of libido like harsh arguments, traumas (physical & emotional), lack of appreciation for one another, infidelity, growing apart, boredom, lack of love & romance.
Take the help of a Counselor & if required a
Psychiatrist. Since you are very young, get treated before the symptoms get worse.
Take adequate sleep, stay away from addictions, eat healthy nutritious homemade food. Come out of monotony. Enjoy life with your fiance.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Nupur K, General & Family Physician
