When Hunger Strike Turns Dangerous

When does a hunger strike become life-threatening? Doctors explain the health risks of prolonged fasting as Sonam Wangchuk’s condition draws concern.

Climate activist and education reformer Sonam Wangchuk’s indefinite hunger strike has entered a critical stage, raising serious concerns about the health risks associated with prolonged fasting. After more than 20 days without food, Wangchuk’s condition reportedly deteriorated significantly, drawing nationwide attention as doctors closely monitor his health.

The protest, which began on June 28 at Delhi’s Jantar Mantar, is aimed at demanding accountability over alleged irregularities in national entrance examinations, including NEET, and calling for broader reforms to improve transparency and fairness in India’s education system.

Since beginning the hunger strike, Wangchuk has experienced significant weight loss and increasing physical weakness. Doctors have warned that extended fasting can lead to severe electrolyte imbalances, muscle wasting, cardiac complications, and damage to vital organs if nutritional deprivation continues, highlighting the potentially life-threatening consequences of prolonged hunger strikes.

What Happens to the Body During a Prolonged Hunger Strike?

Doctors explain that the body does not simply “run out of food.” Instead, it enters a series of metabolic stages designed to preserve life. During the first 24 hours, the body relies on glycogen, the stored form of glucose found in the liver and muscles, to maintain blood sugar levels.

Once these reserves are depleted, the body shifts to burning fat for energy through a process known as ketosis. During this phase, many people experience fatigue, headaches, dizziness, irritability, reduced concentration, and dehydration.

As fasting continues beyond several days, fat stores gradually become insufficient to meet the body’s energy demands. The body then begins breaking down muscle proteins to obtain amino acids needed for essential functions.

This process affects not only skeletal muscles but can also weaken the heart muscle, respiratory muscles, and organs, resulting in rapid weight loss, declining physical strength, weakened immunity, and increasing vulnerability to infections.

Why Doctors Become Increasingly Concerned After Two to Three Weeks

Medical experts say the risk profile changes dramatically once fasting extends beyond two or three weeks. By this stage, the body’s reserves are significantly depleted, and the likelihood of electrolyte disturbances rises sharply.

Electrolytes—including potassium, sodium, magnesium, and phosphate—are essential for maintaining normal heart rhythm, nerve signaling, and muscle contraction. Low potassium, or hypokalemia, is particularly dangerous because it can cause irregular heartbeats, muscle paralysis, respiratory failure, and, in severe cases, sudden cardiac arrest.

Doctors treating Wangchuk have specifically expressed concern over declining potassium levels, one of the reasons authorities decided that continuous hospital monitoring was necessary.

Prolonged starvation can also reduce blood pressure, slow the heart rate, impair kidney function, suppress immunity, and eventually affect liver and brain function. As nutritional reserves continue to decline, the body becomes progressively less able to maintain normal organ function.

What Does Medical Research Say About Hunger Strikes?

Medical guidance on hunger strikes has been extensively discussed in scientific literature. The World Medical Association’s Declaration of Malta on Hunger Strikers, () regarded as the international ethical standard for physicians caring for hunger strikers, states that prolonged fasting requires regular monitoring of hydration, electrolyte levels, cardiovascular function, kidney function, mental capacity, and body weight. It also emphasizes that competent adults have the right to refuse food while ensuring they receive unbiased medical care.

Prolonged starvation increases the risk of cardiac arrhythmias, kidney injury, immune dysfunction, hormonal disturbances, muscle wasting, and multi-organ failure. Studies also highlight that electrolyte abnormalities—not starvation alone—are often responsible for sudden deterioration during extended fasting.

Another important concern identified in medical research is refeeding syndrome. Once food is reintroduced after prolonged starvation, the body’s metabolism changes rapidly, causing phosphate, potassium, and magnesium to shift into cells. If nutrition is restarted too quickly without medical supervision, these electrolyte shifts can trigger heart failure, seizures, respiratory complications, and even death. For this reason, clinical guidelines recommend gradually restoring nutrition while closely monitoring blood chemistry.

Can the Brain Also Be Affected?

The effects of starvation extend well beyond weight loss. As calorie deprivation continues, glucose available to the brain decreases, leading to difficulty concentrating, slower thinking, mood changes, irritability, anxiety, and memory problems.

In advanced starvation, vitamin deficiencies and metabolic disturbances may contribute to confusion and impaired decision-making. Although many hunger strikers remain mentally alert for long periods, prolonged nutritional deprivation places increasing stress on the central nervous system.

Can Someone Recover Fully After a Hunger Strike?

Recovery depends on several factors, including the duration of fasting, the amount of weight lost, hydration status, age, and pre-existing medical conditions. Individuals who undergo prolonged starvation often require carefully supervised nutritional rehabilitation rather than immediately resuming a normal diet. Doctors monitor electrolyte levels, kidney function, heart rhythm, and metabolic markers throughout recovery to prevent complications such as refeeding syndrome.

Why Wangchuk’s Case Has Drawn Medical Attention

Wangchuk’s case has attracted widespread attention not only because of the political significance of his protest but also because it illustrates the medical risks associated with prolonged fasting.

Reports indicate he has lost more than nine kilograms since beginning the hunger strike, while doctors have described his condition as approaching a critical stage if fasting continues. Hospitals in Delhi have been placed on alert, and medical teams have continued twice-daily assessments to identify early signs of organ dysfunction or electrolyte imbalance.

While hunger strikes remain a longstanding form of peaceful protest around the world, physicians stress that extended fasting is never medically harmless. As the days pass, the risk shifts from manageable symptoms such as fatigue and weakness to potentially irreversible complications affecting the heart, kidneys, brain, and other vital organs. Wangchuk’s ongoing fast has once again highlighted the delicate balance between respecting an individual’s autonomy and preventing serious medical harm.
