A chronic (long-term) skin disorder that causes small and discolored bumps or blisters on the skin is called pyoderma gangrenosum. These blisters often join together and form large open sores (ulcers). Healthcare providers do not fully understand why it occurs, but it is often linked to some autoimmune disorders or an earlier skin injury. Commonly, […]

A health condition in which the muscle between the stomach and small intestine narrows or thickens is called pyloric stenosis. Sometimes, it is called hypertrophic pyloric stenosis (HPS), and it may cause forceful vomiting that may lead to malnourishment and dehydration. The muscle located between the stomach and small bowel is called the pylorus. It […]

A rare blood disorder in which the bone marrow no longer produces enough red blood cells is called pure red cell aplasia (PRCA). As a result, people with this disorder also develop anemia (low red blood cell count). In some cases, people develop this condition due to abnormal genes that are inherited from biological parents, […]

A health condition that occurs quite rarely and causes a sudden drop in blood pressure upon standing, and autonomic nervous system problems, is called pure autonomic failure (PAF). PAF often worsens over time, but there are some therapies available to manage the symptoms. In other words, pure autonomic failure is a neurodegenerative disorder that negatively […]

This is a disease in which the heart ventricles (lower heart chambers) contract too quickly and do not have time to fill with blood. It is called pulseless ventricular tachycardia. When there is no blood flow, the pulse stops. This is a medical emergency that requires immediate treatment, including defibrillation. Heart-healthy habits and management of […]

A health condition in which the blood flows with difficulty from the heart muscle to a blood vessel that goes to the lungs is called pulmonary valve disease. This is a serious health condition that may cause multiple health problems because it reduces the amount of oxygen tissues and organs in the body receive. Usually, […]

A health condition where a fetus or baby’s lungs develop improperly is called pulmonary hypoplasia. While it can be present at birth (congenital), doctors may detect this condition on an ultrasound during pregnancy. In most cases, pulmonary hypoplasia occurs due to an underlying condition (such as congenital diaphragmatic hernia or low levels of amniotic fluid). […]
