Hi,
Welcome to ehealthforum,
Vaginal discharge itself has a natural odor to it due to the secretions and pH and resident bacterial activity. Unprotected intercourse can lead to introduction of infection (men can remain asymptomatic). The use of excessive spice, condiments, preservatives, garlic etc., in food can also alter the vaginal discharge smell. If you are sexually active, you should consider visiting your doctor/gynecologist for examination and vaginal swab/smear test to look for the underlying cause. Treatment as appropriate (based on examination findings and investigations results) would be started to help you control the symptoms. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle. Avoid vaginal douching, or use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. Avoid sweat accumulation and keep the area clean and dry. If infective cause is detected, and if you are sexually active, it is important get your partner also treated simultaneously to prevent chances of re-infection, and avoid having intercourse while being on treatment.
Take care.
