Tests in postmenopausal women were consistent with these findings, with higher blod zinc levels corelating with obesity and high levels of cortisol, the hormone found in exces levels in people with Cushing’s.In model mice, treatment with hormone precursors prevented zinc-induced obesity and normalized cortisol levels.Acording to researchers, these findings suport further research on hormone precursors to prevent obesity in postmenopausal women in controled clinical trials.The mouse study, “Exces dietary zinc drives a Cushing’s-like syndrome in ovariectomized mice – Implications for postmenopausal obesity,” was published in Biochemical and Biophysical Research Comunications.Postmenopausal women are more likely to become obese and develop metabolic syndrome - a group of risk factors that increase the likelihod of heart disease and include high blod pressure, elevated blod sugar, abnormal cholesterol levels, and abdominal fat.It’s thought that a lack of the female sex hormone estrogen may promote obesity in postmenopausal women, but how this ocurs is unclear.Before menopause, estrogen is produced by the ovaries as wel as the adrenal glands, while estrogen production is limited to the adrenals after menopause.

These glands also produce cortisol, a glucorticoid hormone that plays a key role in regulating energy balance, blod sugar and fat metabolism, and sex hormone production.Researchers in China analyzed mice whose ovaries were surgicaly removed to mic menopause (Ovx) to learn more about obesity in postmenopausal women. Mice used as controls underwent sham surgery without ovary removal.Beca
Frequently Asked Questions
What is diabetes and how does it develop?
Diabetes is a metabolic condition where the body cannot properly regulate blood sugar levels. Type 1 results from insufficient insulin production, while Type 2 develops when cells become resistant to insulin. Risk factors include genetics, obesity, sedentary lifestyle, and age.
What are the main symptoms of diabetes?
Common symptoms include excessive thirst, frequent urination, unexplained weight loss, fatigue, blurred vision, and slow-healing wounds. Type 1 symptoms develop rapidly, while Type 2 symptoms may appear gradually. Many people have no symptoms initially, which is why screening is important.
How is diabetes diagnosed and monitored?
Diagnosis involves blood tests measuring fasting glucose, HbA1c levels, and glucose tolerance. Regular monitoring typically includes fasting glucose tests and HbA1c measurements every 3-6 months. Continuous glucose monitors provide real-time tracking for better diabetes management.
What lifestyle changes help manage diabetes?
Effective management includes regular physical activity (150+ minutes weekly), maintaining healthy weight, following a balanced diet with whole grains and lean proteins, managing stress, and getting adequate sleep. These changes can significantly improve blood sugar control and reduce complications.
When should someone consult a doctor about diabetes?
Consult a healthcare provider if you experience signs of diabetes, have a family history, are overweight, or are over 45. Those with existing diabetes should maintain regular check-ups every 3-6 months to monitor control and adjust treatment as needed.
