An estimated 3.2% of adults ages 50 or older have very low B₁₂ levels, and up to 20% may have borderline deficiency. Aging is often the cause. Other causes include taking heartburn medications; eating a diet that does not include animal products; weight loss surgery; or autoimmune diseases that attack the stomach lining or gastrointestinal tract. It’s a good idea for older adults to take a B₁₂ supplement of 2.8 micrograms daily to ward off B₁₂ deficiency. People who have very low levels of B₁₂ may need to take a much higher dose or get B₁₂ injections.

Morning back and neck pain are often triggered by sleep position or poor choice of mattress or pillow. Certain sleep poses, especially stomach-down, can lead to pain by creating misalignment of the spine and other areas of the body. To prevent back and neck pain, people can switch sleep positions frequently, align all body areas when shifting positions, use firmer pillows, consider buying a new mattress, and place a foam wedge under the pelvis or between the legs while sleeping.

Clostridioides difficile, a bacterium that causes severe diarrhea and colon inflammation, is common in hospitalized people. New research suggests that even patients who are not diagnosed with the infection in the hospital can bring it home and expose family members.

Recent guidelines suggest a blood pressure reading of less than 120/80 mm Hg as normal. But the ideal number for individuals depends on their individual goals and whether they also have a chronic condition, such as heart disease or kidney disease.

There are many choices for lenses to replace a cataract. Examples include lenses that allow a person to see clearly at a single distance, or at several distances. Some types can correct astigmatism. When deciding which lens to choose for cataract surgery, people should consider costs, daily vision needs, existing vision problems, and pros and cons; for example, some lenses have more vision range than others, but also have risks of glare at night; some lenses still require a person to use glasses for up-close or distance vision.

There's no one sound unique to a particular shoulder problem. That makes it hard to know what various shoulder noises are telling you. Possibilities include arthritis; bone breaks; rotator cuff tears; gas bubbles, loose parts, or bone spurs in the shoulder joint; neck problems; and bursitis. It's advisable to investigate shoulder noises if they happen, along with shoulder pain, weakness, or limited movement, or if the sound followed a shoulder injury. It's also smart (though not urgent) to ask a doctor about shoulder sounds that aren't accompanied by other symptoms.

Joints do not wear out from overuse. Osteoarthritis, the most common type of arthritis, occurs when the smooth cartilage that lines the joint deteriorates. This might occur because of an injury, age, family history, obesity, or a disease that causes joint inflammation.

The problem many people have with sugar is that they consume too much of the refined kind added to many processed food products, and not enough of the natural kind in fruits, vegetables, and grains.
