Causes Of Kidney Disease In Children
Causes of kidney disease in children are numerous. Like in adults, CKD is mostly caused by high blood pressure and diabetes. In recent years however, the rate of children suffering from diabetes and high blood pressure has increased due to the fact that most children nowadays are overweight.
Being overweight greatly increases the risk of developing serious health problems like diabetes, high blood cholesterol, CKD and high blood pressure. It can also cause the child to have to have knee or ankle problems just like in adults.
Causes of kidney Disease in children may be due to various conditions or diseases.
- Birth defect
- Systemic disease
- Hereditary disease
- Urine blockage or reflux
- Nephrotic syndrome
- High blood pressure
Hemolytic Uremic Syndrome and Acute Post-Streptococcal Glomerulonephritis are kidney disease that can develope in children after infection.
- Hemolytic umeric syndrome can be caused by contaminated food such as meat,diary products and juice.
- Post – streptococcal glomerulonephritis can occur after an episode of strep throat or skin infection. The bacterium does not attack the kidney directly, instead the infection may stimulate the immune system to overproduce antibodies. When extra antibodies circulate in the blood and finally deposit in the Glomeruli, the kidneys can be damaged.
These includes renal agenesis ( children born with only one kidney), renal dysplacia ( children born with both kidneys, yet one does not function), ectopic kidney ( children born with both kidneys, but are not located in the right position).
such as systemic lupus erythematosus ( SLE or Lupus) and diabetes,involves many organs or the whole body. Lupus nephritis is kidney inflammation caused by SLE, which is an autoimmune disease.
Surgery, dehydration, burns, bleeding or injury can cause very low blood pressure thereby decreasing blood flow to the kidneys.
These are diseases passed down from the parents onto their children through genes. For example:
- Polycystic kidney disease ( PKD) – characterized by many grape-like clusters of fluid-filled cysts, that makes both kidneys larger over time.
- Alport syndrom – this develops in early childhood and is more serious in male than in female child. This is called by mutation in gene for a type of protein called collagen that makes up the glomeruli.
Urine blockage or reflux
This is a condition where a blockage develops between the kidneys and the urethra. Urine can back up into the kidneys and cause damage.
These are collection of symptoms that indicate kidney failure. It include the following
- Albuminuria – this is a condition where urine contains a high level of albumin ( a protein found in blood).
- Edema – a conditions whereby legs, feet or ankles swell up.
- Hypoalbulminemia – low levels of albumin in the blood.
- Hyperlipidemia – higher than normal fat and cholestrol levels in the blood.
High blood pressure
As in adults, high blood pressure is a common thing among children and the causes are the same. e:g overweight, family history of high blood pressure etc.
When a child is having high blood pressure, make sure that the doctor checks for kidney disease or damage in the child.
