Abnormal PTH levels can signal endocrine or metabolic disorders , including hyperparathyroidism, hypoparathyroidism, chronic kidney disease, or vitamin D deficiency . Understanding what PTH does and how imbalances affect your body is crucial for maintaining long-term metabolic and bone health. 🧬 What Is Parathyroid Hormone (PTH)?
