A preview of an episode, of My Strange Addiction from TLC, spotlighted a woman named Angela, who reports consuming up to 100 cups of coffee per day.
Angela stated that she drinks coffee continuously throughout the day and considers it part of her daily routine.
In a promotional clip for the episode, she said, “Some people think 10 cups of coffee is an addiction. Let me tell you, that is nothing. I could drink a hundred cups of coffee a day. Nobody can drink more than me.”
She added that she prefers oat milk over dairy due to stomach discomfort and enjoys flavored creamers such as French vanilla, hazelnut, and sweet cream. She rotates between breakfast blends in the morning and espresso-based drinks like lattes later in the day.
During a medical consultation shown in the episode, a physician named Dr. Sweta Shah, inquired about her bowel habits. Angela reported experiencing diarrhea every day and indicated that she believed this to be normal.
During the televised consultation, Dr. Shah asked Angela to quantify her intake. Angela stated she drinks “way more than 10 cups” and estimated that she has consumed almost 100 cups in a single day. Dr. Shah responded that this level of intake is “super excessive.”
Dr. Shah explained that scientific evidence suggests about four cups per day is likely the upper safe limit for an average adult, and intake beyond that could lead to caffeine toxicity. She warned that excessive caffeine may increase heart rate, elevate blood pressure, and disrupt the digestive system.
Angela acknowledged having diarrhea daily. When asked whether she experienced diarrhea regularly, she replied that she has it every day and had assumed that was a normal pattern. Dr. Shah clarified that daily diarrhea is not considered normal bowel function.
Caffeine is a known gastrointestinal stimulant. It increases intestinal motility by stimulating smooth muscle contraction in the digestive tract. In high amounts, caffeine may accelerate bowel movements and contribute to loose stools.

The U.S. Food and Drug Administration (FDA) states that up to 400 milligrams of caffeine per day, roughly equivalent to 4–5 cups of coffee, is generally considered safe for most healthy adults. The caffeine content of one cup of brewed coffee averages approximately 80–100 milligrams, depending on preparation.
If Angela consumes 100 cups daily, her estimated caffeine intake could far exceed 8,000–10,000 milligrams per day, depending on brew strength. Such intake is significantly higher than recommended safety thresholds.
Excessive caffeine consumption has been associated with:
Gastrointestinal disturbances, including diarrhea
Increased heart rate (tachycardia)
Elevated blood pressure
Anxiety and restlessness
Sleep disturbances
Dependence and withdrawal symptoms
Dr. Shah also noted that caffeine is technically a drug. While small amounts may be tolerated, consuming extremely high quantities over time can lead to physiological dependence.
Caffeine stimulates gastric acid secretion and increases colon motor activity. According to clinical literature, stimulant-induced diarrhea may occur due to increased intestinal transit time, reducing water absorption in the colon.
Chronic diarrhea can lead to complications including:
Dehydration
Electrolyte imbalances
Nutritional deficiencies
Fatigue
Medical professionals typically assess duration, frequency, associated symptoms, and dietary habits when evaluating persistent diarrhea.
Caffeine is a central nervous system stimulant. Regular high intake can lead to physiological dependence. Withdrawal symptoms, such as headaches, fatigue, irritability, and difficulty concentrating, may occur within 12–24 hours after cessation in habitual users.
The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) recognizes caffeine withdrawal as a clinical condition. While caffeine use disorder is not formally classified as a substance use disorder, problematic use patterns are increasingly documented in medical literature.
In media interviews related to the episode, Angela described feeling energized and excited after drinking coffee and stated that she drinks it “all day long.” She also reported needing to use the bathroom up to 20 times a day.
Healthcare providers generally recommend medical evaluation if an individual experiences:
Persistent diarrhea lasting more than several weeks
Signs of dehydration (dry mouth, dizziness, reduced urination)
Heart palpitations
Severe anxiety or insomnia
Inability to reduce caffeine intake despite adverse effects
Treatment approaches may involve gradual caffeine reduction, hydration management, dietary adjustments, and monitoring for complications.
