Does POTS get progressively worse?

Postural Orthostatic Tachycardia Syndrome (POTS) is a complex condition that affects the autonomic nervous system and can cause debilitating symptoms like dizziness, fainting, and rapid heart rate upon standing. Many POTS patients wonder if their condition will worsen over time. Here is an overview of the progression of POTS.

What is POTS?

POTS is characterized by an abnormally large increase in heart rate when moving from a lying down to standing position. This is accompanied by symptoms like (1):

• Dizziness
• Fainting
• Palpitations
• Fatigue
• Headache
• Nausea
• Brain fog

These symptoms are thought to arise from inadequate constriction of the blood vessels and a resulting reduced blood flow to the brain upon standing up. POTS can affect adults and children, but most commonly occurs in women between the ages of 15-50 years old.

Does POTS get worse over time?

The progression of POTS varies significantly between patients. Some key points on the worsening of POTS include:

• POTS may initially get worse – Many patients report a gradual worsening of symptoms over the first few years after onset, followed by a plateau.
• Progression depends on subtype – There are several subtypes of POTS. Those with neuropathic POTS, associated with autoimmune conditions, often improve in the long run. In contrast, the hyperadrenergic form of POTS may continue to get worse over decades.
• Pregnancy can worsen symptoms – The hormonal changes of pregnancy often temporarily aggravate POTS symptoms. Symptoms usually return to baseline after delivery.
• Menopause may improve symptoms – Loss of estrogen after menopause can stabilize or even improve symptoms in some women with POTS.
• Late stage progression is variable – Long term studies following POTS patients over decades show varied outcomes. Some patients gradually improve, while a subset shows worsening symptoms.

In summary, POTS progression is quite variable between patients and depends on the underlying POTS subtype. While worsening over the first few years is common, the long term course ranges from eventual improvement to continued deterioration.

What factors influence worsening of POTS?

Some key factors that can contribute to worsening POTS symptoms include:

• Menstrual cycle – Fluctuations in estrogen and progesterone levels during the menstrual cycle can exacerbate POTS in premenopausal women.
• Pregnancy – As mentioned, the hormonal and cardiovascular changes of pregnancy often worsen POTS. Symptoms typically improve again after delivery.
• Injuries/surgeries – Physical traumas and surgical procedures that involve immobilization can decondition the body and worsen POTS symptoms.
• Sedentary lifestyle – Physical deconditioning from lack of activity can aggravate muscle weakness and lightheadedness.
• Weight gain – Added body weight makes it more difficult for the cardiovascular system to compensate upon standing.
• Medications – Certain drugs like antidepressants, antihistamines, and diuretics can exacerbate POTS symptoms.
• Poor sleep – Sleep deprivation can substantially worsen several aspects of POTS, including fatigue and cognitive symptoms.
• Stress – Physical or emotional stress can trigger flares of POTS symptoms.
• Low blood volume – This can aggravate the drop in blood return to the heart upon standing.

Avoiding or properly managing these factors may help slow the progression of POTS over the long-term.

Treatments to slow progression

Some of the main treatments that can help stabilize or slow worsening of POTS include:

• Compression stockings – These boost venous blood return to the heart.
• Increasing fluid and salt intake – Helps improve blood volume.
• Exercise training – Slowly building up physical activity can improve conditioning.
• Physical counterpressure maneuvers – Techniques like leg crossing and squatting can attenuate drops in blood pressure.
• Avoiding triggers – Preventing known factors like heat exposure or prolonged standing when possible.
• Medications – Drugs like beta blockers, Ivabradine, or fludrocortisone may be helpful.
• Electrolyte supplements – Some patients benefit from added magnesium, potassium, or vitamin B12.

Research on these treatments demonstrates they can prevent exacerbations, improve quality of life, and in some cases lead to long term remission. Ongoing management is key to stabilizing progression.

Prognosis

The long term outlook for individuals with POTS depends heavily on the underlying cause and proper treatment:

• Many patients see gradual improvement in POTS symptoms over 3-5 years.
• Up to 80% of individuals report experiencing prolonged periods of remission where their POTS is well controlled.
• Some patients do experience progressively worsening symptoms that can significantly impact quality of life.
• With proper management, the vast majority of POTS patients are able to lead active, productive lives.

Researchers are still working to better understand predictors of POTS progression. Key factors likely include POTS subtype, lifestyle, and consistency with treatment. Regular follow up care is important to monitor symptom changes over time.

Conclusion

POTS progression is highly variable. Many patients experience worsening of symptoms in the first few years before stabilizing. While a subset of patients see progressive deterioration, most can achieve remission with proper treatment and lifestyle adjustments. Prompt diagnosis, consistent management, and avoidance of triggers can help optimize long-term outcomes in POTS.
