Typical findings of PCOS are:

• High
  levels of androgens, known as male hormones, but females also synthesize
  them though at lower levels.



• Menstrual
  irregularities.



• Many
  small cysts (fluid-filled sacs) in the ovaries.

Many women with PCOS high levels of circulating
insulin because of inappropriate use of this hormone by the tissues. Excess
insulin appears to increase production of androgen. High androgen levels can
lead to:

• Acne



• Excessive
  hair growth



• Weight
  gain



• Problems with ovulation

The symptoms of PCOS can vary from one woman to
another. Some of the symptoms of PCOS include:

• Infertility
  (not able to get pregnant) because of not ovulating. In fact, PCOS is the
  most common cause of female infertility.



• Infrequent,
  absent, and/or irregular menstrual periods



• Hirsutism:
  increased hair growth on the face, chest, stomach, back, thumbs, or toes



• Cysts
  on the ovaries (as seen on ultrasound)



• Acne,
  oily skin, or dandruff



• Weight
  gain or obesity, usually with extra weight around the waist



• Male-pattern
  baldness or thinning hair



• Patches
  of skin on the neck, arms, breasts, or thighs that are thick and dark
  brown or black



• Skin
  tags: excess flaps of skin in the armpits or neck area



• Pelvic
  pain



• Anxiety
  or depression (so PCOS may explain the fact that you get easily irritated)



• Sleep
  apnea: when breathing stops for short periods of time while asleep

Then again,
the “swollen thyroid gland” that you described warrants evaluation by a doctor
to rule out thyroid gland disease, mainly hyperthyroidism (over active thyroid
gland) which by itself can lead to menstrual perturbations and irritability,
though it does not explain the presence of excess body hair.

Both conditions are treatable and have a good prognosis. I recommend that you seek medical attention for
proper evaluation and management of your case.
