Yellow discharge does not necessarily indicate a health problem, especially if the discharge is a light yellow color. This type of discharge can be common in women who inherently have thicker discharge, especially during ovulation.
However, if there is also foul smell or other symptoms such as itchiness in the genital area or pain when urinating, the yellow discharge may be a sign of infection, like trichomoniasis, gonorrhea or chlamydia.
If you are concerned about yellow discharge, you should see your doctor for assessment to evaluate whether there is any underlying cause and to start treatment as necessary.
