"What Do a Knee Joint and a Kidney Have in Common GOUT. Looking at a real knee with arthritis - you can see gouges in the cartilage and areas that are bone-on-bone. But when we posted about this knee people started asking about another joint condition: gout. WHAT IS GOUT A buildup of urate crystals within joints that causes intense pain during flare-ups. While the knee can be affected the most common site is the big toe - specifically the metatarsophalangeal joint (where your metatarsal meets your phalange). THE KIDNEY CONNECTION: Everyone's body produces urate but people with gout have"

"Joint popping comes in several varieties but the specific type that most are referring to is a product of gas bubble formation inside of a synovial joint. Synovial joints are the most numerous and mobile type of joint in the body. They have an outer fibrous membrane with a deeper synovial membrane that produces synovial fluid. Synovial fluid is a lubricating fluid that aids in reducing friction as the joint moves. Dissolved inside the fluid are gasses such as carbon dioxide nitrogen and oxygen. When the joint is pressed upon in such a way to create more volume (think pulling the bones apart"

"Does Excess Protein Make You Fat Let's Talk Macronutrients First Before answering the protein question we need to understand how your body handles all three macronutrients differently. FAT YOU EAT: Gets stored as body fat most easily - requires almost no conversion. If you eat fat and don't burn it immediately for energy it goes straight into adipose tissue storage. CARBOHYDRATES: Have to go through several steps before becoming body fat: All carbs get converted to glucose (even fructose gets converted by your liver first) Glucose is used for immediate energy needs Extra glucose fills up"

But larger stones That's where the nightmare begins.

THE DEPTH: Even though hair originates from the epidermis (outermost layer) the follicle extends deep down into the dermal tissue - the thick middle layer of your skin. WHY PLUCKING LASTS LONGER THAN SHAVING: Shaving cuts hair at skin level"
