Immune tolerance normally prevents defensive cells from attacking the body. the immune system sometimes attack the body is shaped by patients, clinicians, hospitals and the prevention systems that determine when a problem is detected and treated.

The deeper explanation
The answer follows how biology, exposure, healthcare capacity, prevention and access shape outcomes for different people.
The immediate chain is specific to Why does the immune system sometimes attack the body? : Immune tolerance normally prevents defensive cells from attacking the body. Genes, hormones, infections and environmental exposures can alter that balance. Treatment usually controls inflammation while trying to preserve useful immunity.
The system is constrained by the conditions described in the story. The immune system must distinguish danger from healthy tissue. Autoimmune disease begins when that recognition system loses part of its tolerance. Understanding the deeper picture means connecting technical capability with infrastructure, cost, safety, regulation and the choices people make about deployment. The outcome depends on which pressures are strongest, which resources are available and how the people or institutions involved respond.
The situation can change when the relevant actors alter their behaviour, when a key resource becomes scarce or available, or when a rule changes who can act and at what cost.
The consequences extend beyond the immediate question. Autoimmune diseases can be invisible, unpredictable and chronic, affecting work, family life and access to appropriate diagnosis.
A systems view makes the longer mechanism visible: Starting conditions: History, resources and institutional capacity set the starting position before the visible outcome appears. Limits and trade-offs: Rules, capacity and competing priorities limit which responses are practical, even when several options look possible. Choices and distribution: The outcome depends on who can change those conditions and how its consequences are shared.
For Why does the immune system sometimes attack the body?, the practical outcome turns on Starting conditions, Limits and trade-offs, Choices and distribution. Those details determine what each participant can do next and how the result changes over time. The visible outcome is therefore the end of a chain: a decision changes access to a resource, that change alters behaviour, and the new behaviour affects the next decision.
Why it matters
Autoimmune diseases can be invisible, unpredictable and chronic, affecting work, family life and access to appropriate diagnosis.
The public system around the immune system sometimes attack the body
Pharmaceutical incentives, diagnostic capacity and household income affect who receives effective care and how quickly evidence becomes practice.
The consequences reach public budgets and workplaces: prevention can reduce later costs, while unequal access shifts illness and lost work onto families and communities.
