What causes strong menstrual odor?

Menstrual blood usually has a light fishy smell, not a pungent smell. If there is a pungent fishy odor during menstruation, consider the possibility of endometritis and vaginitis. It is recommended that patients with endometritis or vaginitis wear breathable underwear during menstruation, and sanitary napkins should be breathable, thinner, and replaced in time. After the menstrual period is over, go to the hospital for medical treatment and take female secretions for basic examination. Those with sexual intercourse problems should undergo a gynecological examination to observe the condition of the cervix in the vagina and to check whether they have cervicitis or pelvic inflammatory disease. After the diagnosis is confirmed, medication is used for treatment.

If the urine has a strong fishy smell, the possible reasons are: First, urine extraction or not urinating for a long time. At this time, the urine will evaporate in the bladder, and some ester substances will release abnormal odor, which may manifest as a strong fishy smell. It is usually not accompanied by urethral irritation symptoms such as frequent urination, urgency, and inability to hold urine. At the same time, the urine color may become darker, such as yellow-brown or dark brown.

Second, if there is an infection in the urinary system, such as urethritis, cystitis, pyelonephritis, etc., the presence of bacteria that dissolve the protein in the urine can cause a more pungent smell. It may also contain cellular metabolites, bacteria, or concentrated fluids, which can increase the smell of urine.

Third, if there is sugar, protein, or total bilirubin, urobilinogen, etc. in the urine, it may cause an abnormal smell in the urine. It is recommended to conduct a urine test for further identification.
