People with borderline personality disorder (BPD) face a significantly shortened life expectancy, estimated at 13 to 27.5 fewer years than the general population. That’s a wide range, and where any individual falls within it depends on several factors: suicide risk, physical health, substance use, and whether they receive effective treatment. The picture is serious but not hopeless, especially given that the majority of people with BPD eventually experience symptom remission.
Why the Life Expectancy Gap Is So Large
A reduction of 13 to 27.5 years is striking, and it reflects two overlapping threats. The first is suicide. The second, less discussed but equally important, is chronic physical illness. Both hit people with BPD harder and earlier than the general population, and the combination accounts for the wide mortality gap.
The risk is especially concentrated in younger age groups. People with BPD who die prematurely tend to do so earlier in life than those with many other psychiatric conditions, which pulls the average life expectancy down substantially.
Suicide Risk in BPD
BPD carries the highest suicide risk of any major mental health condition: 45 times that of the general population. For comparison, depression increases suicide risk by about 20 times, bipolar disorder by 17 times, and schizophrenia by 13 times. BPD is estimated to account for 9 to 33 percent of all suicides.
A 2025 meta-analysis covering nearly 35,000 people with BPD found that about 80 percent experience suicidal thoughts at some point, roughly half attempt suicide during their lifetime, and approximately 6 percent die by suicide. That 6 percent figure, while lower than older estimates that placed it closer to 10 percent, still represents an enormous toll. The difference likely reflects improvements in treatment and crisis intervention over the past two decades.
Suicidal crises in BPD tend to be driven by intense emotional pain and impulsivity rather than the prolonged hopelessness more typical of depression. This means that effective crisis support and skills for managing overwhelming emotions can make a real difference in survival.
Physical Health Problems
Suicide gets the most attention, but physical illness is a major and underrecognized driver of early death in BPD. Research shows that up to 50 percent of people with BPD have at least one serious medical condition, and these conditions appear at rates far exceeding what you’d expect.
The numbers are sobering. People with BPD have eight times the risk of heart disease and stroke compared to those without the diagnosis. The most common physical health problems include obesity (affecting about 34 percent), high blood pressure or hardened arteries (28 percent), arthritis (28 percent), cardiovascular disease (15 percent), and gastrointestinal conditions (12 percent). The risk of metabolic problems like high blood sugar and abnormal cholesterol is roughly double that of the general population.
Chronic pain is another significant burden. Across multiple studies, about 30 percent of people treated for chronic pain meet the diagnostic criteria for BPD, and people with BPD consistently report higher pain levels than those without the condition. Living with persistent pain affects sleep, activity levels, stress, and overall health in ways that compound over years.
How Substance Use Compounds the Risk
Substance use disorders are extremely common alongside BPD and accelerate both the suicide risk and the physical health decline. One large survey found that about 51 percent of people with a lifetime BPD diagnosis also had a substance use disorder in the previous year. A longitudinal study found that 62 percent of BPD patients met criteria for a substance use disorder at the start of the research period.
The relationship goes both directions. Alcohol and drugs increase impulsivity and worsen the emotional instability that defines BPD, making suicidal crises more dangerous. At the same time, long-term substance use damages the liver, heart, and immune system, contributing to the physical health problems already elevated in this population. Even after periods of sobriety, relapse rates remain high: about 40 percent for alcohol and 35 percent for other drugs. New substance use disorders also develop at notable rates (around 21 to 23 percent), meaning the risk doesn’t simply disappear with initial recovery.
Prescription drug misuse deserves special mention. Nearly 50 percent of people with BPD report a history of prescription drug abuse, and among people seeking treatment for opioid addiction, over 40 percent meet criteria for BPD. Opioid use carries its own acute mortality risk from overdose, layered on top of everything else.
Why These Health Problems Develop
The connection between BPD and poor physical health isn’t random. The emotional dysregulation at the core of BPD triggers a chronic stress response in the body. When your system is flooded with stress hormones on a regular basis, it takes a measurable toll on your cardiovascular system, metabolism, and immune function over time. This biological wear and tear accumulates even without other risk factors.
On top of that, the behavioral patterns common in BPD, such as impulsive eating, substance use, inconsistent sleep, and difficulty maintaining routines, all contribute to conditions like obesity, diabetes, and heart disease. Emotional distress can also make it harder to keep up with medical appointments, follow treatment plans, or seek help for physical symptoms before they become serious. The result is that physical conditions often go unmanaged longer than they would in someone without BPD.
Remission Rates Offer a Different Picture
The life expectancy statistics paint a grim picture, but they don’t capture an important reality: BPD symptoms improve substantially for most people over time. Long-term follow-up studies show that 85 to 93 percent of people with BPD no longer meet the diagnostic criteria after 10 years. That’s a remarkably high remission rate compared to many other psychiatric conditions.
Remission doesn’t mean all difficulties vanish. Many people continue to struggle with relationships, employment, or residual emotional sensitivity even after the core symptoms ease. But the intense impulsivity, self-harm, and suicidal behavior that drive the most dangerous outcomes tend to decrease significantly with age and treatment. The highest-risk period is generally the first several years after diagnosis, particularly in young adulthood.
Effective psychotherapy, particularly approaches designed specifically for BPD that focus on building skills for tolerating distress and managing intense emotions, accelerates this process. People who engage in structured treatment tend to reach remission faster and maintain it more reliably than those who don’t.
What Actually Influences Individual Outcomes
The 13-to-27.5-year gap is a population-level statistic, not a sentence. Several factors push individual outcomes in either direction. Access to consistent mental health treatment is one of the strongest. So is whether co-occurring substance use gets addressed. The presence or absence of a stable support network matters, as does engagement with physical healthcare for the chronic conditions that develop silently over years.
People with BPD who achieve remission of their psychiatric symptoms, manage substance use, and receive regular medical care for physical health conditions can expect outcomes much closer to the general population. The mortality gap is widest for those who fall through the cracks of both the mental health and medical systems, particularly those whose physical health problems go unrecognized because clinical attention focuses solely on the psychiatric diagnosis.
