Larissa Waters Steps Down as Greens Leader Due to Chronic Kidney Disease

• Greens leader Larissa Waters announced her resignation on Monday night, citing a health downturn from pre-existing chronic kidney disease.
• While only 7.4 per cent of Australian adults self-report having the condition, biomedical data indicates that about 14 per cent show clinical signs of chronic kidney disease.
• Experts note that patients often lose a lot of kidney function before experiencing noticeable symptoms such as fatigue, malaise, or itching.

The Silent Progression of Chronic Kidney Disease

The human body relies on the kidneys to filter blood and remove metabolic waste products. Jonathan Craig, vice president and executive dean of the College of Medicine and Public Health at Flinders University, explains that while individuals do not need their kidneys to operate at full capacity, disease occurs when function drops below the threshold required to prevent toxic accumulation.

Because the decline is gradual, symptoms typically remain absent during the early and moderate stages. Affected individuals often do not notice clinical signs until kidney function has fallen to 20, 30, or 40 per cent. Early indicators such as tiredness, malaise, and itching are frequently non-specific, leading many to discover the condition through routine blood and urine testing when recovery is no longer possible.

National Prevalence and High-Risk Demographics

Epidemiological figures highlight a stark gap between awareness and actual prevalence. Only 7.4 per cent of Australian adults self-report having chronic kidney disease, yet biomedical markers reveal that approximately 14 per cent show signs of the condition. Chris Forbes, chief executive of Kidney Health Australia, describes the condition as a silent killer, noting that 50 per cent of people living with the disease die prematurely of a heart attack or stroke, with an estimated 2.5 million Australians harbouring undiagnosed signs.

Vulnerability to the condition is not evenly distributed across the population. Aboriginal and Torres Strait Islander people experience disproportionate levels of kidney disease. Regardless of whether they reside in urban, regional, or rural areas, Indigenous Australians are twice as likely to develop kidney disease and four times as likely to die from it compared to the general population. In remote and very remote areas, the incidence rate of kidney failure climbs up to 20 times higher than that of non-Indigenous Australians.

Underlying Causes and the Burden of Treatment

Diabetes stands as the leading cause of chronic kidney disease in Australia, accounting for approximately 36 per cent of new cases. Additional drivers include high blood pressure, immune diseases, congenital conditions, and inherited genetic disorders. When the disease advances to complete kidney failure, treatment options narrow significantly. For patients requiring organ replacement or dialysis, Jonathan Craig points out that quality-of-life studies indicate outcomes worse than those associated with certain cancers. Dialysis requires patients to be attached to a machine three times a week for up to five hours per session, representing a severe physiological and lifestyle burden.

Prevention and Lifestyle Interventions

Mitigating the risk of chronic kidney disease involves managing established systemic health factors. Jonathan Craig points to standard interventions such as smoking cessation, dietary modification, regular physical activity, and appropriate blood pressure and diabetes management. While genetic disorders and aging remain unavoidable, newer therapeutic agents such as SGLT2 and GLP-1 receptor agonists have demonstrated utility in helping certain patients with diabetes prevent downstream renal complications.
