 [ Symptoms ] since late last year l have been complaining about my loss of appetite and consequently loss of weight [ Disease ] weight loss can be related to abnormal thyroid functions leading to increased level of thyroid hormones or hyperthyroidism that can lead to weight loss secondly frequent mensus can be due to causes related to reproductive system like hormonal imbalances ovarian cysts etc approaching menopause can also cause similar problems so consult a gynaecologist and get a thorough evaluation done along with investigations like cbp hormonal profile pelvic ultrasound etc hope this helps
