Now, let’s dive into the depths of understanding cystinosis and the ten symptoms that characterize this rare disease.

Symptom 1: Excessive Thirst and Urination – A Thirst that’s Hard to Quench

Excessive Thirst and Urination - A Thirst that's Hard to Quench

Cystinosis often presents its first clues in the form of unquenchable thirst and frequent urination, medical terms for which are polydipsia and polyuria, respectively. This increased thirst may not seem alarming at first, given the varied thirst levels among different individuals. However, when coupled with excessive urination, it could be a sign of an underlying condition like cystinosis.

This symptom arises due to the disease’s impact on the kidneys, which are one of the first organs to bear the brunt. The kidneys play a vital role in maintaining fluid balance, a function that gets impaired as cystinosis progresses. This impairment results from the accumulation of cystine crystals within the renal cells, leading to a condition known as renal Fanconi syndrome.

This syndrome is an essential element of nephropathic cystinosis, a common form of the disease. Here, the kidneys’ ability to reabsorb nutrients, salts, and water from the urine is compromised. Consequently, the body starts losing these essential substances, leading to excessive thirst as the body tries to compensate for the loss.

Additionally, the kidneys’ ability to concentrate urine is affected, leading to the production of large volumes of dilute urine. This results in more frequent trips to the bathroom, even during the night, a condition known as nocturia. Such disruptions can negatively impact a child’s sleep cycle, overall well-being, and quality of life.

The duo of unquenchable thirst and frequent urination is a key symptom of cystinosis. It may not seem overly concerning at first glance, but understanding its underlying cause is vital for early diagnosis and management. (1)
