Vomiting is never an enjoyable experience, and sadly this symptom is a very popular side effect of kidney failure. Patients experience the itchy skin first, then the constant nausea, followed by a few days of vomiting. Add in the foul taste when eating foods, and this often creates a further feeling of general sickness. Those who suffer from kidney failure often confusing this vomiting/nausea symptom for the flu or even food poisoning and don’t seek treatment for their kidney issue early enough to prevent it from becoming severe. Being tuned into the early warning signs, and seeking advice from your family doctor, is key, when it comes to kidney failure.
