Bea Alonzo reveals she has hypothyroidism

Bea Alonzo just revealed she has hypothyroidism.

Hypothyroidism or an underactive thyroid is a condition in which the thyroid gland doesn't make enough hormones to address your body's needs.

Symptoms include weight gain, infertility, fatigue, trouble tolerating the cold, and joint and muscle pain, among others.

"Aside from having PCOS, I recently was diagnosed with hypothyroidism so that's the reason behind my gaining weight," Bea said on her vlog.

PCOS stands for polycystic ovary syndrome, a condition in which the ovaries produce an abnormal amount of abnormal male hormones that are usually present in women in small amounts.

Symptoms also include weight gain, difficulty getting pregnant, irregular periods or no periods at all, and oily skin or acne, among others.

"I'm trying to address it now by working out, by dieting, and taking meds for it and supplements. So, wish me luck, sana matapos na siya," Bea said.

"So sa mga nagsasabi diyan, 'Bakit ang taba na daw ni Bea?' 'Yun po 'yung reason. Pasensya na po kayo," she added.

Bea can next be seen in "Ang Larawan: The Concert," with Jericho Rosales and the upcoming GMA TV series, "Love Before Sunrise," with Dennis Trillo.
