Can patients with stones eat eggs?

Whether a stone patient can eat eggs depends on the exact type of stone. There are two main groups: Hepatobiliary stones (gallbladder or bile-duct stones) Pathogenesis: anything that raises the cholesterol-to-bile-acid ratio or causes bile stasis can provoke stone formation. Egg issue: yolks are rich in cholesterol and stimulate gall-bladder contraction, which may precipitate biliary colic or acute inflammation. Recommendation: avoid eggs, especially yolks, as well as other high-cholesterol foods (offal, fatty meats) and stimulants such as alcohol and coffee that increase gall-bladder motility. Urinary-tract stones (kidney, ureter, bladder) Pathogenesis: calcium oxalate, calcium phosphate, uric acid or mixed stones. Egg... Learn more

Can patients with gallstones eat goose eggs?

Whether a patient with gallbladder stones can eat goose eggs cannot be answered with a simple “yes” or “no.” If a small amount causes no discomfort, it is usually permissible. If it triggers pain or other symptoms, the food should be avoided or strictly limited. Dietary guidelines for gallstone patients generally emphasize a low-fat, light diet, but this is not absolute. Goose eggs—especially the yolks—are relatively high in cholesterol, which may provoke a gallstone attack in some individuals. However, many patients tolerate normal foods such as goose or chicken eggs without any flare-up, whereas others experience symptoms even on a... Learn more

Can patients with stones drink tea?

Tea is not recommended; plain boiled water is preferred.From the standpoint of stone-forming mechanisms: Excessive excretion of stone-forming substancesIncreased urinary calcium, oxalate or uric acid from prolonged immobilization, hyperthyroidism, idiopathic hypercalciuria, distal renal tubular acidosis, etc. Low urine volumeRaises the concentration of salts and organic matrix. Reduced urinary inhibitors of crystallizationLower levels of citrate, pyrophosphate, magnesium, acidic glycosaminoglycans and trace elements. Anatomical factors & infectionUrinary-tract obstruction causes stasis and local deposition; infection further promotes struvite or calcium-phosphate stones.Uric-acid stones are linked to gout. Oxalate metabolismOxalate is the second major component of calcium-oxalate stones, yet most patients have no inherited oxalate... Learn more

Can patients with stones eat yogurt?

Stone-forming patients can safely drink yogurt. Its benefits include: Stimulates gastric-juice secretion, improving appetite and digestion. Lactic-acid bacteria lower levels of certain carcinogens, giving anti-cancer potential. Suppresses putrefactive bacteria and the toxins they produce in the gut. Helps reduce blood cholesterol, valuable for people with hyperlipidaemia. Stone patients should also eat plenty of fresh vegetables and fruit, get adequate rest, and limit spicy, greasy or otherwise irritating foods.

Can patients with stones eat tofu?

Stone-forming patients can safely eat tofu.Both gypsum-set (calcium sulfate) and brine-set (magnesium chloride) tofu contain very little oxalate, and further-processed products such as dried tofu are also low in oxalate. During production, soybeans are soaked for hours, so most of the soluble purines leach out; the curd is then diluted with large amounts of water, further lowering purine concentration.Moreover, the calcium supplied by tofu is beneficial: dietary calcium binds oxalate in the gut, reducing its absorption and lowering urinary oxalate—an important protective factor against calcium-oxalate stones. Therefore, patients with kidney stones do not need to avoid tofu.The key precautions are:... Learn more
