Traditional Chinese medicine believes that eating carambola in summer can clear away heat and detoxify, promote fluid production to quench thirst, moisten lung and resolve phlegm, lower qi, harmonize middle energizer, and induce diuresis to relieve stranguria. People think that eating carambola can treat body heat, polydipsia, wind-heat cough, oral erosion, sore throat, toothache, joint pain, carbuncle, gangrene, swelling, poison, traumatic swelling and pain.

Although eating carambola has many benefits, for some patients with kidney disease, eating carambola may aggravate the condition. The mechanism of carambola aggravating renal damage is unclear, which may be related to the following factors:

1, carambola contains a natural toxin, the composition of which is not very clear. However, animal experiments have confirmed that carambola contains irritating neurotoxin, which may be oxalate. Oxalate is nephrotoxic, which can damage glomerular capillary basement membrane and epithelial cells, leading to hematuria, but this statement has not been confirmed by large-scale clinical trials.

2. For patients with renal basic diseases or uremia, renal damage will be further aggravated due to neurotoxin excretion disorder.

3. The mechanism of hematuria caused by carambola is related to allergic reaction. Carambola enters the body as an antigen, which causes pathological reaction due to the hypersensitivity of the body, leading to renal tissue damage and hematuria. However, the mechanism of allergic reaction is extremely complicated, and further research is needed to clarify the detailed mechanism of hematuria.

Knowing why you can't eat carambola because of kidney disease, you should reduce your choice of carambola because of kidney disease, and in normal times, patients with kidney disease should not eat too much salt, which is not good for your health. Patients should also pay attention to this.
