Q and A: about health and research

Chronic hyponatremia is a medical condition in which the concentration of sodium in the blood falls below 135 mEq/L for 48 hours or longer. Sodium is one of the body’s most important electrolytes. It helps regulate fluid balance, nerve signaling, muscle contraction, and normal brain function. When sodium levels decline gradually over time, the body attempts to adapt, particularly within the brain. Although this adaptation reduces the immediate danger of brain swelling, chronic hyponatremia is far from harmless. For many years, chronic hyponatremia was often considered “mild” or “asymptomatic,” especially when sodium levels were only modestly reduced. Research now shows that even mild chronic reductions in sodium can significantly affect cognition, balance, bone health, and overall physical function. The condition is especially common among older adults, hospitalized patients, individuals taking certain medications, and people with chronic illnesses involving the heart, kidneys, liver,...

Introduction My understanding of hormonal dysfunction dates back to 1979, when I was diagnosed with low cortisol levels at the age of 30 at the Erlangen Clinic. This diagnosis finally explained my long-standing symptoms of persistent fatigue, muscle weakness, and declining metabolic and immune function. Additionally, my son has been diagnosed with acromegaly, further deepening my awareness of endocrine disorders. Despite the available scientific literature and advancements in medical knowledge, it took nearly three decades before another endocrinologist in New Mexico ordered an ACTH test in 2007. This personal journey underscores a broader issue in the medical community: the lack of awareness and timely diagnosis of endocrine disorders. The endocrine system and function   What is a Primary Endocrine Disorder? A primary endocrine disorder occurs when one endocrine gland stops working correctly. In contrast, a secondary endocrine disorder arises when a master gland (such as the p...
