Introduction
Urinary incontinence is defined as the involuntary leaking of urine. This implies that a person urinates when they do not want to. Pregnancy, delivery, diabetes, and having a higher body mass index all raise the risk of urine incontinence. It occurs when control of the urinary sphincter muscle is lost or impaired.
It is a common problem that is distressing and affects 423 million individuals worldwide. Approximately 13 million Americans suffer from urine incontinence. UI is more common in women than men and is thought to affect around 25 percent of premenopausal and 40 percent of postmenopausal women. UI not only causes physical discomfort; it also causes psychological distress and social shame, thus lowering the quality of life of a patient.
While traditional therapies such as drugs and surgical procedures provide a varied degree of comfort, they have some risks and limitations. This has resulted in growing interest in alternative medicine, with acupuncture emerging as a promising option.
Acupuncture is particularly beneficial for pain relief; however, it is currently being explored and utilized to address disorders such as urinary incontinence. Few studies support acupuncture or acupressure as a viable therapy strategy for urine incontinence; hence, further studies are needed to prove the efficiency of these treatments. This article briefly explains acupuncture for treating urinary incontinence and its mechanism.
What Is Urinary Incontinence?
Urinary incontinence is characterized by problems with bladder control and urine leakage, which can impact everyday activity. The urinary system comprises the kidneys, ureters, bladder, and urethra. These organs filter, store, and eliminate waste from the body. Kidneys filter waste from the blood, producing urine. The urine then travels through the ureters to the bladder for storage. Once the bladder is full, the brain signals the need to urinate, and the bladder releases the urine through the urethra when the urinary sphincter muscle opens. In a healthy urinary system, urination is well controlled, allowing time to reach the toilet without leakage. Urinary incontinence occurs when this process malfunctions, which can happen for various reasons.
There are several forms of incontinence, each with its causes. The types of incontinence are as follows:
-
Stress Urinary Incontinence: It is the involuntary leaking of pee caused by urethral sphincter muscle or pelvic floor weakness when intraabdominal pressure rises during exertion, effort, sneezing, or coughing.
-
Urge Urinary Incontinence: This is the involuntary leaking of pee due to an overactive bladder muscle called the detrusor—the muscle contracts too often or too strongly even when the bladder is not full.
-
Mixed Urinary Incontinence: As the name suggests, this is an involuntary pee leakage induced by a mix of stress urinary incontinence and urge urinary incontinence.
-
Overflow Urinary Incontinence: In this condition, the bladder does not empty. This happens when the muscle that pushes urine out (the detrusor muscle) is weak and not strong enough to empty the bladder fully. This can occur due to nerve damage caused by conditions like spinal cord injuries, multiple sclerosis, or diabetes. Sometimes, it can occur when a bladder outlet is blocked, which prevents urine from flowing out freely. This happens commonly due to an enlarged prostate in men.
-
Functional Urinary Incontinence: The involuntary flow of pee caused by physical or environmental obstructions to toileting.
What Is Acupuncture?
Acupuncture is a traditional Chinese medicine (TCM) used for over 2,000 years. TCM is a healthcare system that has evolved over thousands of years to treat, diagnose, and prevent illness. The process involves inserting solid, hair-thin metallic needles into specific points on the skin. According to TCM, the human body has around 400 acupuncture points.
These points lie along an energy pathway known as meridians, the pathways through which energy moves. The energy is called Qi (pronounced "chee"). The concept of Qi is central to acupuncture. Practitioners believe that imbalances in Qi flow can lead to various health issues. By stimulating acupuncture, the aim is to restore Qi balance. Acupuncture is used to address a wide range of conditions, including urinary incontinence.
How Does Acupuncture Work to Treat Urinary Incontinence?
The exact mechanism by which acupuncture may alleviate urinary incontinence has yet to be fully understood. Some studies suggest acupuncture treats urinary incontinence by stimulating nerves, muscles, and brain regions involved in bladder control.
1. Autonomic Nervous System: The autonomic nervous system controls bladder function and other involuntary actions of the body.
-
Sympathetic Nerves: This helps to relax the detrusor muscle, allowing the bladder to store urine.
-
Parasympathetic Nerves: This helps contract the detrusor muscle, helping the bladder empty.
2. Somatic Nervous System: This part of the nervous system helps to control voluntary action. It controls the external urethral sphincter muscle, which allows it to hold or release urine.
These systems work together smoothly for normal bladder function. Incontinence happens when this balance is disrupted, which could lead to overactive bladder muscles, weak bladder muscles, or problems with sphincter muscles. Specific acupressure on the lower back, lower abdomen, and legs are selected due to their connection to the bladder control system.
Acupuncture points are chosen to stimulate the sympathetic and parasympathetic nerves of the autonomic nervous system involved in bladder control. To facilitate the somatic nervous system, specific acupuncture points are located at the origin of the pudendal nerve, which controls the pelvic floor muscles and sphincter. Stimulating these nerves with acupuncture can influence bladder function by preventing urine leakage.
Some acupuncture points, like ST36, are believed to increase levels of neurotransmitters that are important for bladder function. When acupuncture is done at this point, it activates a part of the brain, which increases the serotonin neurotransmitter levels. This helps to control the bladder and urination by activating the pudendal nerve.
What Does Research Say About the Effectiveness of Acupuncture for Urinary Incontinence?
Some studies suggest that acupuncture might be helpful with urinary incontinence, but the evidence is not strong enough. More significant, better-designed studies are needed to truly understand if acupuncture is an effective treatment for urinary incontinence.
Conclusion
Urinary incontinence is a complex condition. Acupuncture offers a promising alternative or complementary treatment option. By addressing the condition through mechanisms such as stimulating the autonomic and somatic nervous systems, acupuncture can significantly improve the symptoms and quality of life of individuals with urinary incontinence.
