Hi,thanks for using healthcare magic
Depression is a severe illness that can have a profound negative impact on a person's life. There are certain criteria that are used to diagnose depression and at least 5 of them must be present for at least 2 weeks. The criteria are depressed mood most of the time, loss of interest in activities, weight or appetite change, sleep disturbance, fatigue or loss of energy, feeling worthless, suicidal ideas, decreased concentration or ability to think.
Once diagnosed then treatment is best, it involves
counselling and the use of medication for a short time.
The increased in weight may or may not be linked to the depression.If she is depressed , she would not have the drive or energy to do anything about her weight right now, so the depression needs to be treated first.
Persons with PCOS tend to have increased weight, the
metformin would be useful here because it would decrease the
insulin resistance associated with PCOS and may help with the weight.In persons who experience GI problems with metformin, it is advised to start at a low dose - about 250 mg and increase slowly as tolerance to it improves.
Weight loss helps with PCOS- it reduces the insulin resistance and improves
fertility.
In terms of the prolonged bleeding , this can be due to a number of factors such as hormonal imbalances, abnormal levels of the thyroid hormone, structural problems with the uterus (identified on
Ultrasound)
I hope this helps
