Yes, alcohol can cause blood in stool, but usually indirectly. Alcohol itself does not typically damage the colon lining enough to make it bleed. Instead, heavy drinking causes bleeding through irritated stomach lining, liver damage that leads to swollen veins in the esophagus and rectum, or by triggering diarrhea that irritates tissue.

You can prevent neck wrinkles better than most people realize, because the neck is not doomed to age faster than your face. The core strategy dermatologists rely on is simple: protect the neck from ultraviolet light every single day, extend your facial skincare down past the jawline, and stop assuming the neck takes care of … Read more
RNA sequencing measures gene activity by counting short fragments of RNA. The counting is never perfectly even. Some samples yield more RNA than others, some steps in the lab capture RNA more efficiently than others, and some genes are simply easier to detect than others. External RNA Controls Consortium (ERCC) spike-ins are a set of … Read more
Yes, Covid-19 can cause low blood pressure, though it is far less common than the well-known respiratory symptoms. When it happens, it usually falls into two groups: a drop during the acute infection itself, or a lingering drop that some people notice weeks to months later. The first is well documented in hospital settings. The … Read more

For most people it is annoying rather than dangerous. For some it is bothersome enough to affect daily life and, occasionally, to make … Read more

A typical starting amount is about 1 to 2 tablespoons of a single-ingredient puree once or twice a day, gradually increasing as your baby gets used to eating. That small amount surprises … Read more
Puppy diarrhea is common, and most cases in young puppies trace back to a short list of causes: sudden diet changes, intestinal parasites, stress, eating something they shouldn’t, or infections. The fix depends entirely on which one is behind it. Some cases clear up with simple at-home care. Others need a vet quickly, especially in … Read more
A helmet only protects you when it fits right and sits in the right place. The front edge should sit about one to two finger-widths above your eyebrows, the straps should form a V just under each ear, and the chin strap should be snug enough that the helmet does not shift when you shake … Read more
A tampon goes into your vagina. That is the muscular canal that runs from the vaginal opening on the outside of your body to your cervix. It does not go into your urethra, where urine comes out, and it does not go into your anus. It also does not get lost inside you, because the … Read more
Aquaphor does not treat acne. It contains no ingredients that fight acne bacteria, unclog pores, or reduce oil production. It is an ointment designed to seal in moisture and protect damaged skin, and for some people with acne it can make breakouts worse by trapping oil and debris against the skin. That said, the answer … Read more
