A spirometer measures how much air your lungs can hold and how quickly you can move it out. You read the results by comparing two key numbers — FEV1 and FVC — against predicted values based on your age, height, sex, and ethnicity. The ratio between them tells your doctor whether airflow is blocked, whether … Read more
Your breathing rhythm during a run is set largely by your pace and how hard your muscles are working, not by willpower. The most reliable way to regulate it is to slow down until you can breathe through your nose or hold a short conversation, then let your breathing settle into a steady rhythm on … Read more
Diarrhea is not the classic symptom of pancreatitis, but it can happen. The pancreas makes enzymes that break down fat and proteins, and when it is inflamed or damaged, that enzyme output can drop. Undigested fat then passes through the gut, producing loose, greasy, foul-smelling stools. So diarrhea can be a sign of pancreatitis — … Read more

Freeze dried fruit is the crunchy stuff in trail mix that tastes like a strawberry but weighs almost nothing. The short answer: it is real fruit, and it keeps most of what makes fruit healthy. The catch is that it also concentrates the sugar and calories into a much smaller package, so portion size matters … Read more
An ultrasound image is a map of sound echoes, not a photograph. A device sends high-frequency sound waves into the body, and the machine builds a picture from the waves that bounce back. That is why the same organ can look bright in one image and dark in another, and why learning to read one … Read more
Grapevines clone more easily than almost any other fruiting plant. You cut a dormant stem in winter, plant it in soil, and it grows roots and becomes a genetically identical vine. The method is called hardwood cutting propagation, and home gardeners have used it for centuries. Here is the short version. Take a cutting from … Read more
Most infants learn to roll from back to stomach between 4 and 6 months of age. This is a gross motor milestone, and the timing can vary widely from baby to baby. Some infants figure it out closer to 3 months, while others wait until 7 or 8 months — and both can fall within … Read more
