Vibrating Feeling in Your Uterus? Here’s All You Need to Know

A strange feeling of vibration in any part of your body can make you worry. And that worry can be greater if you feel it around your uterus. Many women experience a vibrating feeling in the region of the uterus.

If you suffer from this too, you may be wondering, ‘should I be worried about this vibrating uterus?’ 

Most of the time, it’s no cause for concern. However, if it’s persistent, then it might be worth looking into. Vibrating uterus can be due to various causes. But they’re mostly caused by pelvic muscle spasms. And bowel movements can sometimes be felt as a vibration at the lower abdomen as well.

Let’s take an in-depth look at how this vibrating or twitching sensation occurs.

Vibrating Uterus

There are many structures in the lower abdomen. And the twitching or vibrating sensation can come from any of them. The nerves supplying the organs inside the body aren’t the same as the sensory nerves of the skin. So, it’s possible that the vibrating sensation is in any structure of the lower abdomen.

A most common cause of a vibrating feeling is a pelvic floor muscle spasm. Fetal movements during pregnancy can be an important cause as well. Other than that, gas transit throughout the gastrointestinal tract can be responsible too.

Let’s take a look at the normal structures of the pelvis to better understand where the vibrating sensation can be.

Normal Structures in a Pelvis

There are several important organs and structures in the pelvis. The pelvic cavity is a continuation of the abdominal cavity down below. Unlike the thoracic cavity, the pelvic cavity doesn’t have physical separation from the abdominal cavity.

The pelvic cavity is surrounded by the bony pelvis. The two pelvic bones form the front and the sides of the pelvis. And the sacrum and coccyx form the back of the pelvis. The sacrum and coccyx are the continuations of the spine down below.

There are many muscles lining the inside of the bony pelvis. These muscles are the pelvic floor muscles. The important muscles are obturator internus, piriformis, levator ani, coccygeus, etc. These muscles form almost a hammock upon which the various pelvic organs sit. There are also various membranes and ligaments.

Inside the pelvis, there are several organs. At the very front, there’s the urinary bladder. This lies just behind the pubic bone. Behind and above this is the uterus. The uterus continues below into the vagina. A pair of fallopian tubes with an ovary at each end is also present inside the pelvis.

Behind the uterus are the parts of the gastrointestinal tract. The sigmoid colon and the rectum comprise the gastrointestinal tract in this portion. However, loops of the intestines can also be present just above these structures.

There are other structures like blood vessels, nerves, two ureters, etc.

Causes of a Vibrating or Twitching Feeling in the Lower Abdomen

As we’ve seen that the uterus is in the middle of the pelvic cavity. So, any twitching feeling in the pelvic cavity might give you the feeling that you have a vibration in your uterus.

Let’s take a look at some of the most common causes:

Pelvic Floor Muscle Spasm

We’ve seen that the pelvic muscles basically form the floor of the pelvis. So, they support the pelvic organs. Some of these muscles even have important constrictor functions. For example, the willing constriction of the urethra, anus, and vagina is done with the help of these muscles.

These are voluntary muscles. And like any other muscle, they can twitch or spasm. And this twitch or spasm is felt in the lower abdomen. So, this may be perceived as a vibrating uterus. 

The uterus is composed entirely of smooth muscles. These muscles don’t have the same nerve supply as your regular voluntary muscles. So, you’ll not experience the same vibrating sensation. But the pelvic floor muscles are striated voluntary muscles. So, it’s possible for them to have a vibration or twitch.

The pelvic floor muscles are intimately connected with these various systems. So, different types of abnormalities might cause them to spasm. 

Some of the important causes are:

Anxiety and Stress

An anxious state of mind or too much stress can lead to muscle spasms. Anxiety and stress can lead to some changes in the brain and various chemicals. These chemicals are neurotransmitters that control signal transmission through nerves. These chemicals also play a role in muscle contraction.

So, the altered state of neurotransmitters in anxiety could be the reason why muscle spasm occurs more. Besides this, altered breathing during anxiety can lead to a change in pH as well as a change in ion concentration. This can lead to muscle spasms as well.

Drugs and Chemicals

Several drugs and chemicals can bring about changes to muscle activity. Taking too much coffee can make muscle spasms frequent. Besides that, alcohol and certain drugs can cause this too.

Childbirth

The stress of childbirth can put a heavy toll on the muscles of the pelvis. Research shows that pelvic muscle spasm increases with the number of childbirths. So, this can be the reason for this vibration or twitching as well.

Excessive Muscle Strain

Putting too much strain on the pelvic muscles makes them prone to spasms. If you do too much unbalanced exercise, then this might happen. If you suffer from chronic constipation, then you might be putting too much strain on your pelvic muscles as well.

Obesity

Being overweight has various health implications. And women who are obese tend to have more pelvic muscle spams. The pelvic muscles have to do more work to support the weight. That’s why this might be responsible as well.

Vaginismus

This is a primary condition of pelvic muscle spasms. This can happen to anyone and there are no definitive causes. However, scientists do believe that there is a neurological basis.

In this disorder, there are painful contractions of the pelvic muscle. This is especially so during intercourse. So, this can create several problems down the line.

Other conditions

Besides these, several other reasons may be responsible for pelvic muscle spasms like

  • Increasing age
  • Pelvic surgery
  • Injury or trauma to the pelvis
  • Pelvic infection
  • Menopause
  • Fatigue and dehydration, etc.

Bowel Movement

Bowel movements might give a vibrating feeling too. There are various parts of the gastrointestinal (GI) tract inside the pelvis. So, a sensation there might be perceived as a vibrating uterus as well.

This can be caused due to normal gas movement. As food gets digested, gas is produced in the intestines. So, this gas may give off that sensation too.

Some intestinal diseases like infection, allergic diseases, indigestion, etc. can sometimes cause a twitching feeling in the gut as well.

Fetal Movements

Pregnancy is an important cause of a fluttering feeling in the abdomen. This can be due to various causes. Fetal movements can sometimes be perceived as a flutter. This phenomenon is known as quickening. This appears around 16-20 weeks of pregnancy. You have nothing to worry about. This is normal and an indication of a healthy fetus.

The baby can also kick during the later stages of development. The uterine vessels also pulsate during this period due to increased blood flow. But, it’s more likely that the vibration is due to fetal movements.

Other Causes

There are other possible causes of a vibrating feeling in the lower abdomen. Many women complain of a vibrating feeling during ovulation or during the beginning of their period. This is nothing serious and doesn’t last long.

Sometimes, abnormal arterial pulsation can be felt like a vibrating uterus as well. This can be due to increased blood supply which sometimes can be a sign of neoplasm. However, this is highly unlikely.

When to See a Doctor?

So, is this vibrating uterus something you should be worried about? In most cases, it’s nothing to worry about. And if it occurred only once or twice and didn’t return, then you should be fine.

However, if this occurs frequently, then it might require attention. This may indicate pregnancy or even serious conditions. So, it’s best to see a doctor if you feel these vibrations constantly. Also if you have other symptoms like pain, fever, difficulty in urination, etc. then you should see a doctor too.

FAQ

Can the womb vibrate?

Answer: It’s highly unlikely for the womb or the uterus to vibrate. The uterus contains smooth muscle. These are different from your regular skeletal muscles in the limbs and other parts of the body. Twitch or vibration is normally seen in skeletal muscles.

Why do I feel vibrations in my lower abdomen?

Answer: You might feel vibrations in the lower abdomen due to gas movement in the intestines, fast bowel transit, allergic reaction to food, muscle spasm, fetal movements, etc.

Is it normal to feel flutters not pregnant?

Answer: There can be various reasons other than pregnancy that cause fluttering in the abdomen. This can be due to gas, allergic reaction, muscle spasm, etc.

Conclusion

The vibrating uterus can be due to various causes. Most commonly this is not a cause of concern. But if it continues for days, do not handle the situation lightly. 

It’s best to go see a doctor in order to rule out any severe conditions. Also, he will be able to prescribe medicine or suggest lifestyle changes if necessary.
