Your liver makes glucose around the clock, even when you have not eaten for hours. It does this mainly through a process called gluconeogenesis, where the liver builds new glucose from other molecules like lactate, glycerol, and amino acids. It also stores glucose as glycogen and releases it between meals. The most effective way to … Read more
Infertility is defined by how long you have been trying, not by how you feel. If a couple has regular unprotected sex for 12 months without pregnancy, that meets the standard medical definition of infertility. For women 35 and older, the timeline shortens to 6 months. Most of the time there are no obvious signs … Read more
Pneumococcal disease is caused by a bacterium called Streptococcus pneumoniae. The PPV23 vaccine works by introducing purified sugar coats, called polysaccharides, from 23 of the most common strains of this bacterium into the body. The immune system recognizes these sugars as foreign and produces antibodies against them, so it is better prepared if a real … Read more
When food poisoning hits, the most important thing you can take is fluid — specifically, water mixed with electrolytes to replace what your body is losing through vomiting and diarrhea. That matters more than any food, supplement, or remedy in the first hours. Solid food comes later, once your stomach has settled, and even then … Read more

Skip hot water, skip fabric … Read more

That figure holds for the standard half gallon sold in the United States, which is a volume of 64 fluid ounces, or about 1.89 liters. Whole milk lands near that number, and the other types sit close to it too, because the difference … Read more
If you notice aching in your back, hips, legs, or shoulders right as you try to settle into bed, you are not imagining it. The discomfort is real, and it usually comes from one of a handful of causes: an inflammatory condition that flares when you stop moving, a mattress or sleep position that puts … Read more
Toilet paper dust is made of tiny paper fibers that shed from the roll every time you tear off a sheet. To eliminate it for good, you have to change what the fibers do after they leave the roll: keep them from becoming airborne in the first place, capture the ones that do, and reduce … Read more
Vitamin C does not appear to increase kidney stone risk for most healthy adults at typical dietary intakes. The concern comes from a real biochemical pathway: when the body breaks down vitamin C, one of the end products is oxalate, and oxalate is the main building block of the most common type of kidney stone. … Read more
Home pregnancy tests work by detecting a hormone called human chorionic gonadotropin, or hCG, in your urine. That hormone starts building up in your body only after a fertilized egg implants in the uterus, which usually happens about six to twelve days after ovulation. Because of that biology, testing too early is the single most … Read more
