Generally in advanced cases of kidney failure, protein diet restriction is advised.
The protein products like meat and fish, which we eat get degraded in our body and these degraded metabolites act as toxins, since the chronically ill kidneys can’t flush them out of the body. Healthy kidneys would be successfully removing such toxins.
When these metabolites of protein accumulate they can aggravate the nitrogenous compound load on kidney and worsen the feeling of nausea, vomiting and other uremic symptoms. Furthermore, they can damage the kidney by increasing its filtration and more proteins might drain out of the body. It’s bit complex to understand properly.
Is there any negative consequence of protein restricted diet?
Yes. As protein is an essential component of our health since our muscles and various other organs are made of protein, lack of protein can cause an under-nourished health condition (referred as protein energy malnutrition). Therefore, total or absolute protein restriction is also not desirable.
How much protein should you consume if you have a chronic kidney disease?
Ask your health care provider how much protein should you consume. Based on individual person’s health status the requirement might vary from person to person.
In normal health condition on average an adult produces about 1-2 litres of urine per day.
Polyuria is passing of excessive volume of urine.
Generally when the amount of urine passed is more than 2.5-3 litres per day in an adult, it’s called polyuria.
Polyuria is classically seen in diseases like diabetes mellitus and diabetes insipidus.
Those people who are suffering from diabetes and taking insulin probably become happy when their doctor decreases their dose of insulin or stops insulin.
But if a person is suffering from chronic kidney disease along with diabetes, decrease in insulin doses may not be something to be happy.
When chronic kidney disease deteriorates i.e. progresses to advanced stages, the requirement of insulin falls in diabetics.
Now the question is:
Why insulin requirement falls in advanced stages of chronic kidney disease?
- In advanced stages of chronic renal failure, the kidneys excretion capacity of insulin molecules decrease, therefore more of the insulin remains in blood. Unless the insulin gets excreted normally the further requirement of insulin is less. In such scenario your doctor might decrease your insulin doses.
Ask you doctor today to be sure why your insulin dose was decreased.
Chronic kidney disease develops after an insult to the kidney for many years. Once developed it’s not reversible. Treatment is mainly focussed to slow down the damaging process to the kidney and the overall health.
Two things basically play role in prevention of progression of chronic kidney disease:
- Good control of blood pressure is very important to minimise the damage to the kidneys.
- Low protein diet to decrease the load of potassium and nitrogenous waste on the kidneys (since kidneys are responsible for getting our body freed from the nitrogenous waste burdens, so the weak kidney’s workload reduces).
