Thank you for asking!
  I am Dr S Khan and i would like to answer your query for your daughter who has PCOS, Asthma, Mood swings and night sweats.
1-Lets start with PCOS.
  Al the symptoms of fasting blood sugar irregular menses and borderline blood pressure, increased TAGs are because of this trouble. Now PCOS needs a proper care and once managed all the metabolic symptoms will get back to normal. Losing weight and a regular exercise is the first step here.Remember diet and lifestyle modification is the first step here.Get ADA diet for diabetics. Increase omega 3 .and 9 fatty acids.Vitamin D supplements. increased fiber; decreased refined carbohydrates, trans fats, and saturated fats is necessary.Remember  diet low in cholesterol and saturated fats and increasing physical activity is the key here.
Medications used in the management of PCOS include the following:
Oral contraceptive agents (eg, 
ethinyl estradiol, 
medroxyprogesterone)
Antiandrogens (eg, spironolactone, leuprolide, finasteride)
Hypoglycemic agents (eg, metformin, insulin)
Selective estrogen receptor modulators (eg, clomiphene citrate)
Topical hair-removal agents (eg, eflornithine)
Topical acne agents (eg, 
benzoyl peroxide, tretinoin topical cream (0.02–0.1%)/gel (0.01–0.1%)/solution (0.05%), adapalene topical cream (0.1%)/gel (0.1%, 0.3%)/solution (0.1%), erythromycin topical 2%, clindamycin topical 1%, 
sodium sulfacetamide topical 10%)
 If the above mentioned options did not help then their are surgical options too like
Electrocautery
Laser drilling
Multiple biopsy etc.
Seek an 
Endocrinologist for ACTH stimulation test to rule out hormonal issues or for other causes of menstrual irregularity such as 
thyroid disease or pituitary adenoma. A reproductive endocrinologist should be consulted if the patient is infertile and desires pregnancy.
2-Now Mood swings:
  A 
psychiatrist is needed here. Some psychotherapy sessions with vocational recreational therapies will help.
3-Snoring issues:
  Once the weight is lost, snoring will vanish,Seek an otorhinolaryngologist for snoring sleep apnea. Discuss option like CPAP, BIPAP therapies with them and let them help the patient.A consult to a sleep disorder specialist would be  nice for PSG studies.
4-Asthma needs prevention of stimuli and triggers and compliance with medication.Immunologist and pulmonologist would help further.
Following Endocrinologists are famous in chorlotte.
