It's definitely a trend, and the handwriting is on the wall for anyone using chimpanzees in research. Public sentiment has also turned against using chimpanzees, especially in invasive studies, after decades of studies on the apes revealed their intelligent, emotional natures to be similar to our own.
Best Answer: CONCLUSION: Weight gain and elevated body weight are frequently associated with prolactinomas regardless of a mass effect on the hypothalamus or pituitary function. In this series, weight loss was recorded in 70% of prolactinomas patients and in 90% of male patients who normalized their prolactin levels. We propose the inclusion of hyperprolactinaemia in the differential diagnosis of endocrine obesity and weight gain.
These high prolactin levels are often caused by prolactinoma, which causes a tumor to grow on your pituitary gland. This tumor then excretes excess prolactin in your body. Rarely, liver disease, kidney disease, polycystic ovary syndrome (PCOS), shingles or hypothyroidism may cause high levels of prolactin.
