Chronic medical issues are frustrating for both doctors and patients, who just want to feel better. Tammie Robie, 51, struggled for nearly 20 years with blood pressure that was resistant against multiple medications. She pushed through her days as a wife, mother, teacher and competitive runner. Dr. Sanjay Dixit, the medical director for Quest Diagnostics, said PA was considered uncommon for many years. “Primary aldosteronism occurs when the adrenal glands produce too much aldosterone, a hormone that helps regulate sodium and potassium in the blood,” he said. The adrenal glands are located on top of the kidneys. According to Dixit, the Endocrine Society recommended in 2025 that all patients with hypertension be evaluated for PA. He notes that nearly half of all adults, or nearly 120 million people, have high blood pressure.

Postpartum body odor and sweating are common and generally not a cause for concern. Hormonal changes, milk production, and excess fluid shedding contribute to postpartum body odor. Damian Pat Alagia III, MD, MS, MBA, medical director for women’s health at Quest Diagnostics, explains that a pregnant person gains up to 10 pounds of amniotic fluid, blood, and other fluids.“Once the baby is born, the fluid needs somewhere to go," Dr. Alagia adds. Because of this, postpartum parents often experience increased sweating. "This is the body’s way of flushing out these excess fluids.”
