Hi, Symptoms of kidney failure are - Loss of apatite, nausea, vomiting, generalized weakness, altered sensorium. - Symptoms due to water retention like swelling over face, legs, weight gain, breathing difficulty. - Decreased urine production. In your case there is possibility of decreased kidney function (kidney failure) as there is presence of risk factors like uncontrolled hypertension. I want to know your ultrasound report. You need to consult your doctor there is a need for clinical examination depending on it further evaluation can be done. Blood test for kidney function is necessary in your case. Other tests like complete blood count, urine examination for proteins, serum electrolytes, calcium, phosphorus, arterial blood gas analysis, ECG, 2DEcho of heart may be necessary. Hope this may be helpful to you, if so do vote.
