How the Pelvic Floor Functions in Lymphatic Drainage: Understanding Anatomy, Symptoms, and Therapy

By Dr. Christine Martirez PT, DPT on 9/9/2024

The pelvic floor plays a significant role in the body’s overall function, including its ability to support lymphatic drainage. The pelvic floor is often associated with urinary, bowel, and sexual health, but it also has a key role in the lymphatic system, which is responsible for removing waste and excess fluids from tissues.

In this blog post, we’ll explore the anatomy of the pelvic floor, how it supports lymphatic drainage, symptoms of pelvic floor congestion, and how pelvic floor physical therapy can help.

Anatomy of the Pelvic Floor

The pelvic floor is composed of a complex group of muscles, ligaments, and connective tissues that span the base of the pelvis. These muscles support the pelvic organs (such as the bladder, rectum, and uterus or prostate) and help with functions like urination, defecation, and sexual function.

The key muscles of the pelvic floor include:

• Pubococcygeus (PC) Muscle

  : Part of the levator ani group, this muscle controls urine flow, contracts during orgasm, and supports the pelvic organs.

• Puborectalis

  : This muscle helps maintain continence by forming a sling around the rectum and supporting its function.

• Iliococcygeus

  : Another part of the levator ani group, this muscle assists in lifting and supporting the pelvic organs.

• Obturator Internus

  : This muscle stabilizes the pelvis and supports pelvic floor function during movement.

• Coccygeus

  : Supports the tailbone and helps with stabilizing the pelvic region.

All of these muscles work together to maintain the function of the pelvic floor, but they also interact with the body’s lymphatic system by promoting movement of lymphatic fluids through gentle muscle contractions.

How the Pelvic Floor Supports Lymphatic Drainage

The lymphatic system plays a crucial role in keeping the body healthy by draining excess fluids, cellular waste, and toxins from tissues and returning them to the bloodstream for removal. The pelvic floor, being a key group of muscles at the base of the body, plays a direct role in encouraging lymphatic fluid movement from the lower body back toward the heart.

Through normal pelvic floor muscle contractions, the lymphatic vessels in the pelvis and lower abdomen are stimulated, promoting fluid drainage from tissues. The rhythmic contractions of the pelvic floor muscles help to pump fluid through the lymphatic system, supporting the body’s natural detoxification process.

However, when the pelvic floor becomes congested or dysfunctional, it can negatively affect lymphatic drainage, leading to symptoms of pelvic floor congestion.

Symptoms of Pelvic Floor Congestion

Pelvic floor congestion occurs when lymphatic flow is impaired, resulting in a buildup of excess fluid and toxins in the pelvic region. Common symptoms of pelvic floor congestion include:

• Pelvic Pain or Pressure

  : Feelings of heaviness or fullness in the pelvic area.

• Swelling or Edema

  : Fluid retention in the lower abdomen, legs, or genital area.

• Urinary Issues

  : Increased urgency or frequency of urination due to pressure on the bladder.

• Bloating

  : Feelings of discomfort or bloating in the lower abdomen due to poor fluid circulation.

• Fatigue

  : Generalized feelings of tiredness and sluggishness, as the body is less able to remove toxins and waste.

• Hemorrhoids or Varicose Veins

  : Congestion in the pelvic area can lead to increased pressure in blood vessels, causing these conditions.

If left unaddressed, pelvic floor congestion can lead to a range of chronic conditions and reduce overall quality of life.

How Pelvic Floor Physical Therapy Can Help

Pelvic floor physical therapy is an effective way to address pelvic floor dysfunction and congestion by promoting proper muscle function, improving lymphatic flow, and alleviating symptoms. Here’s how pelvic floor physical therapy can help:

1. Manual Therapy

   : A pelvic floor physical therapist may use manual techniques, such as myofascial release, to release tightness in the muscles and tissues of the pelvic floor, improving lymphatic circulation. Soft tissue manipulation helps release tension, increase blood flow, and encourage lymph drainage.

2. Pelvic Floor Muscle Training

   : Therapists often prescribe specific exercises to strengthen and relax the pelvic floor muscles. Proper muscle engagement and relaxation help stimulate lymphatic movement and reduce fluid retention.

3. Postural Alignment and Movement Education

   : Poor posture, particularly in the pelvis and lower back, can hinder lymphatic drainage. Pelvic floor physical therapy addresses postural issues by teaching proper alignment, which can enhance the natural flow of lymphatic fluids.

4. Diaphragmatic Breathing

   : Proper breathing techniques are essential for lymphatic health, as the diaphragm’s movement directly impacts the pelvic floor and lymphatic flow. Diaphragmatic breathing exercises can help improve the coordination between the diaphragm and pelvic floor muscles, promoting better fluid movement.

5. Downregulation of the Nervous System

   : Chronic stress or hyperactivity of the nervous system can affect the function of the pelvic floor and lymphatic system. Therapists may incorporate relaxation techniques to reduce muscle tension and improve lymphatic drainage.

6. Education on Lifestyle Modifications

   : Physical therapists will also provide guidance on hydration, diet, and movement habits that support lymphatic health. Staying well-hydrated and adopting daily practices like regular movement can significantly boost lymphatic drainage.

The pelvic floor plays an important role not only in supporting your pelvic organs but also in promoting lymphatic drainage and overall health. Dysfunction or congestion in the pelvic floor can lead to uncomfortable symptoms such as swelling, pain, and urinary issues. Pelvic floor physical therapy can help restore normal function, improve lymphatic flow, and alleviate symptoms of congestion through manual therapy, muscle training, and postural education.

If you’re experiencing pelvic floor congestion or related symptoms, pelvic floor physical therapy could be the key to improving your lymphatic health and overall well-being.
