Hello,
I have gone through your query and understand your concern.
Your problems are
1. Weight gain
2. Irregular menstrual cycles
3. Enlarged thyroid gland
4. High
prolactin levels.
High prolactin levels could be due to either
hypothyroidism ( enlarged throid glands) or Poly cystic ovarian disease.
But prolactin level may also be little bit elevated in stressful conditions.
Weight gain also could be either due to
Polycystic ovarian disease or hypothyroidism.
To confirm the diagnosis, requires further tests and observation.
1. Complete thyroid hormone profile
2. Prolactin levels in blood
3.
Ultrasound abdomen and pelvis
4. Blood sugar fasting and postprandial
5. Liver function tests.
Depending on what is found to be the cause, the treatment varies.
For example, if these symptoms are due to hypothyroidism, then supplement of
thyroxine hormone will be the usual treatment.
Hope this helps.
Please write back for further queries.
Wishing you good health.
