Your digestive system is a 30-foot-long tube that runs from your mouth to your anus, and it does far more than break down food. It turns a sandwich into fuel for every cell in your body, hosts trillions of bacteria, and contains its own nervous system with roughly 500 million neurons. It also works around … Read more
Chia seeds are tiny, nutrient-dense seeds that can be part of a healthy diet, but there is no single official daily amount. Most healthy adults can eat about 1 to 2 tablespoons (roughly 12 to 24 grams) per day, an amount that fits within common dietary patterns and provides fiber, protein, and healthy fats without … Read more
Prostatitis can change the color, thickness, and consistency of semen, and in some cases it can affect fertility. The prostate produces roughly 20 to 30 percent of the fluid that makes up semen, so inflammation in that gland can alter what a man sees in the ejaculate and, less often, how well sperm function. Most … Read more
Can drinking cause thyroid problems? The short answer is yes, but only in specific situations. Alcohol can affect the thyroid in several ways, though the effect depends on how much you drink, how often, and whether you already have an underlying thyroid condition. The relationship is real but often overstated in casual conversation. The thyroid … Read more
Switching from the Dexcom G6 to the Dexcom G7 is mostly a matter of getting a new prescription and setting up a new sensor. The G7 is a different device with a different app, a different transmitter design, and a shorter warm-up period, so you do not simply swap one sensor for another the way … Read more
Pain in the upper part of your stomach usually points to one of a handful of structures: the stomach itself, the first section of the small intestine, the esophagus, the gallbladder, the pancreas, or the liver. That area — roughly from the bottom of your breastbone to just above your belly button — is crowded … Read more
Blood sugar is the amount of glucose circulating in your blood right now. For most adults without diabetes, a normal fasting blood sugar is between 70 and 99 mg/dL. Two hours after a meal, it usually stays below 140 mg/dL. Those two numbers are the foundation of how doctors define normal, and almost everything else … Read more
An AQI of 87 means the air is moderately polluted. An AQI of 187 means it is unhealthy for everyone. The number is not a measurement of pollution itself — it is a translation of pollutant concentrations onto a single 0-to-500 scale, so you can judge air quality at a glance. The scale runs from … Read more
Medical ethics applies to almost every decision made in healthcare. It shapes how doctors talk to patients, how research is designed, how scarce organs are allocated, and what happens when a family disagrees with a treatment plan. It is not a set of abstract ideals kept in a textbook. It is the working framework that … Read more
Most coughs are not the problem — they are the solution. A cough is a reflex your body uses to clear irritants, mucus, or germs from your airways, and it usually fades on its own within a few weeks. The goal of treatment is not to silence the reflex completely but to calm it enough … Read more
