Can dialysis patients drink coffee? At present, coffee has been many people’s essential drink, and they are used to drinking one or two cups of coffee every day. Many dialysis patients also have this habit, but their doctors often recommend them to avoid coffee. Is this statement right?

However, for people on dialysis, either hemodialysis or peritoneal dialysis, they still need to follow a restricted diet plan. This is because dialysis can’t regulate inner body system as effectively as healthy kidneys. Additionally, dialysis can also cause some side effects and complications such as sleep problems and bone disease.
Coffee is one caffeine-containing drink, and it also contains some specific substances like tannic acid. These substances may lead to some disorders for dialysis patients.
Firstly, coffee can worsen patients’ high blood pressure. With kidney failure, blood pressure increases easily. If you also have high blood pressure, you may need to stay away from coffee. This is because caffeine has a vasoconstrictive property that can increase the pressure against vascular walls. Also, it may trigger headache.
Secondly, coffee can worsen calcium loss. Bone disease or osteoporosis is one common complaint of kidney failure, because of calcium deficiency. Caffeine can stimulate more calcium discharged out of the body, so it can increase the risk of bone disease.
Finally, coffee may cause sleep problem. Many patients on dialysis are tormented by sleep problem, because of muscle cramps, weakness or other problems. If you drink one cup of coffee before bedtime, you may find it is more difficult to fall into sleep or stay sleep all the night.
