Obesity and polycystic ovary syndrome have a strong connection, as women with PCOS are usually overweight. Though, it is possible to have PCOS and be healthy or even underweight. This is known as a lean polycystic ovarian syndrome. Women who have lean polycystic ovarian syndrome may have to deal with irregular periods, blood sugar control, fertility problems, and other manifestations because of increased androgens' levels (testosterone), which can cause excess facial hair and acne. The signs of being lean or obese because of polycystic ovarian syndrome begin soon after having periods for the first time. The production of insulin in women with PCOS is either excessive, or the insulin they produce does not work or affects the way it should. The inefficiency of insulin to function ordinarily is one main reason women with PCOS conduce to gain weight or face hardship in losing weight.
PCOS is an outcome of hormonal imbalance and the inability of the body to regulate the insulin appropriately, which is made inferior because of an unhealthy or junky diet, a lazy lifestyle, and overweight. It is impossible to hear from a gynecologist that conceiving naturally with PCOS is possible because the chances are slender to none.
The polycystic ovarian syndrome is firmly associated with obesity. Overweight women are easily diagnosed with PCOS in their teenage, mainly if they have very irregular or absent period cycles. Comparatively, lean women with PCOS usually remain undiagnosed for years. They may not be diagnosed with PCOS until they struggle to conceive. Lean PCOS treatment for women is possible for women who can comprise hormone replacement treatment (most commonly used, oral contraceptives), egg donor, blood sugar-regulating medicines, IVF to conceive, or adoption.
Women with lean polycystic ovarian syndrome know that these are not the only options. Women can also improve their health by consuming a PCOS-specific, nutrient-dense, whole food diet.
Why does polycystic ovary syndrome cause weight gain?
PCOS makes it challenging for the body to exercise the hormone insulin, which usually helps transform sugars and starches from foods into energy. This ailment is called insulin resistance.
Increased insulin level is the primary cause of excessive production of male hormones (androgens), and high androgen levels lead to body hair growth, acne, irregular periods, and excessive weight gain. Male hormones trigger weight gain, typically in the abdomen portion, and abdominal fat is the unhealthiest fat type because it is associated with an augmented heart disease risk and different health conditions.
Slow Metabolism
Women with PCOS fight fierce cravings and tend to feel hungry all the time, which leads to excessive weight gain.
Appetite Control
There are several hormones involved with hunger and appetite control. Women dealing with PCOS are not satiated even after consuming heavy meals. This means that women dealing with PCOS will continue to feel hungry, even if they have had all of the nutrients and calories that their body requires.
This is the story for many women with PCOS. They gain weight quickly and strive to lose it because of:
• Difficulties with insulin
• Slower metabolic rate
• Disordered appetite control
