Understanding POTS: Insights from Christina Applegate’s Daughter Sadie’s Diagnosis

Recently, Christina Applegate’s daughter, Sadie, disclosed her diagnosis of Postural Orthostatic Tachycardia Syndrome (POTS) during an episode of the “MeSsy” podcast, which Applegate co-hosts with Jamie-Lynn Sigler. This revelation has sparked interest and questions about the condition, its symptoms, causes, and treatments. Here’s a comprehensive look into POTS, a condition that affects the autonomic nervous system, and its impact on daily life.

What is POTS?

Definition and Mechanism

Postural Orthostatic Tachycardia Syndrome (POTS) is a condition that impacts the autonomic nervous system, which regulates involuntary body functions such as heart rate and blood pressure. According to the Cleveland Clinic, POTS causes your heart to beat faster than normal when you transition from sitting or lying down to standing up. This occurs because the body’s autonomic nervous system fails to coordinate the balancing act of blood vessel constriction and heart rate response, leading to unstable blood pressure.

Symptoms of POTS

Symptoms of POTS can vary widely among individuals but often include:

  • Fatigue: Persistent tiredness that can interfere with daily activities.
  • Lightheadedness: Feeling dizzy, especially upon standing, which can sometimes lead to fainting.
  • Brain Fog: Difficulty in concentrating and thinking clearly.
  • Heart Palpitations: A sensation of the heart pounding or skipping beats.
  • Nausea and Vomiting: Digestive disturbances are common.
  • Headaches: Frequent and severe headaches.
  • Excessive Sweating: Abnormal sweating patterns.
  • Shakiness: Trembling or shakiness, especially in the limbs.
  • Exercise Intolerance: Difficulty in performing physical activities.
  • Discoloration: Pale face and purple discoloration of the hands and feet, especially when the limbs are lower than the heart level.

These symptoms can be exacerbated in warm environments, situations that involve prolonged standing, during illness, or after inadequate intake of fluids and salt.

Sadie’s Experience with POTS

During the podcast, Sadie, 13, described her experiences with POTS, particularly the challenges she faces when standing up. “I feel like I’m gonna pass out. I have fainted before, and I have gone unconscious, but that doesn’t usually happen. That’s only on really bad days when it’s hot out,” she explained. This personal account highlights the debilitating nature of POTS and its potential to significantly impact daily living.

Causes and Triggers of POTS

Underlying Factors

POTS can be triggered by various factors, including:

  • Pregnancy: Hormonal and physiological changes can trigger the onset of POTS.
  • Major Surgery: The physical stress from surgery can lead to the development of POTS.
  • Trauma: Physical or psychological trauma can be a trigger.
  • Viral Illnesses: Viruses like influenza, parvovirus, and COVID-19 have been linked to the onset of POTS.


The COVID-19 pandemic has brought increased attention to POTS, as many individuals report the onset of symptoms following a COVID-19 infection. Dr. Svetlana Blitschteyn, a neurologist and director of the Dysautonomia Clinic, noted that viral infections are the most common trigger for POTS. In her research, she has identified POTS as a common syndrome among long-haulers, individuals who experience prolonged symptoms after recovering from COVID-19.

One such case is Jarred Arfa, who was diagnosed with POTS about a year after contracting COVID-19. “These patients are young people in their 20s, 30s, and 40s who were healthy or had minor medical problems that didn’t impact their lives before, and now they are experiencing extreme fatigue, dizziness, headache, inability to exercise, and some are unable to work,” Blitschteyn explained.

Treatment Options for POTS

No Cure, But Manageable

While there is currently no cure for POTS, several treatment options can help manage its symptoms. These include:

Lifestyle Changes

  • Diet Modifications: Increasing salt and fluid intake can help manage blood pressure.
  • Regular Exercise: Gradual and consistent exercise, particularly aerobic activities, can improve symptoms.
  • Compression Stockings: Wearing compression garments can help prevent blood from pooling in the legs.


  • Beta-Blockers: These medications can help control heart rate.
  • Fludrocortisone: Helps retain salt and fluid in the body.
  • Midodrine: Increases blood pressure by constricting blood vessels.

Professional Guidance

Consulting with a healthcare professional is essential for developing a personalized treatment plan. Specialists can provide tailored advice and adjust treatment strategies based on individual needs and symptom severity.

Other Celebrities with POTS

Sadie is not alone in her battle with POTS. Other celebrities have also come forward about their experiences with the condition. Singer Halsey revealed her diagnosis in 2022, bringing further awareness to the condition. Television personality Bethenny Frankel also opened up about her struggles with POTS last year. These public disclosures by well-known figures have helped to shine a light on POTS, encouraging others to seek diagnosis and treatment.


POTS is a challenging condition that affects the autonomic nervous system, leading to symptoms such as dizziness, fatigue, and heart palpitations. While it is not life-threatening, it can significantly interfere with daily life. Sadie’s candid discussion about her experience with POTS on the “MeSsy” podcast has brought much-needed attention to this condition. Understanding POTS, its symptoms, causes, and treatment options is crucial for managing the condition effectively. With increased awareness and ongoing research, there is hope for better management strategies and improved quality of life for those affected by POTS.
