"I feel like my lower back is arched."
"My lower back gets tired easily when I stand for long periods."
"My lower back hurts when I sleep on my back."
"I'm worried about my protruding belly."

Do you have any of these concerns?

An exaggerated lumbar curve is often not just a matter of posture, but is frequently related to pelvic tilt, hip joint stiffness, and difficulty using the abdominal and gluteal muscles .

Women, in particular, tend to develop an exaggerated arch in their lower back due to factors such as wearing heels, poor posture while standing, muscle imbalances, and physical changes after childbirth.

This time, we will explain the common physical characteristics of people with lordosis (excessive curvature of the lower back) and the points that should be reviewed during chiropractic treatment.


What is lordosis (excessive curvature of the lower back)?

An exaggerated curvature of the lower back is a condition where the curve of the lower back is excessively pronounced.
A characteristic feature is that the pelvis tends to tilt forward, making the lower back appear excessively arched.

In appearance,

  • My stomach tends to stick out.
  • My buttocks tend to stick out backwards.
  • The front of my thighs tend to get tight.
  • The back appears arched.

These characteristics tend to become more apparent.


Feature ① The front of the thighs tends to get tight.

People with an arched lower back tend to put more strain on the front of their thighs.

When the pelvis tilts forward, the front of the hip joint and the front of the thigh tend to become tense.
the result,

  • My thighs get tired just from standing.
  • My thighs tend to get really tight in the front.
  • My lower body looks bulky.

This can lead to conditions like these.


Feature ②: Prone to developing a protruding belly.

People with an exaggerated lumbar curve may appear to have a protruding stomach.

This isn't just a matter of fat; it's often related to pelvic tilt or difficulty using abdominal muscles.

especially,

  • Lower abdomen tends to protrude.
  • Even when I strain, my stomach doesn't easily flatten.
  • Trying to improve my posture only makes my lower back arch more.

If this sounds like you, it might be due to an exaggerated curvature of the lower back.


Feature ③ Difficulty using the gluteal muscles

People with an exaggerated lumbar curve may not be using their gluteal muscles effectively.

Normally, the glutes are important muscles that support the pelvis and hip joints, but when you have an exaggerated lumbar curve, you tend to rely more on your lower back to support the weight.

the result,

  • My lower back hurts when I stand.
  • My lower back gets tired easily when I walk.
  • I don't feel like I'm using my glutes very well.

This can lead to a situation like this.


Feature ④: Stiffness in the front of the hip joint

People who spend a lot of time sitting at a desk or doing desk work tend to develop stiffness in the front of their hip joints.

When the front of the hip joint becomes stiff, the pelvis is pulled forward, which tends to increase the curvature of the lower back.

especially,

  • My lower back doesn't stretch easily after sitting for a long time.
  • I feel a tightness in the front of my hip joint.
  • My stride is getting shorter.

If this sounds like you, it might be related to stiffness in the front of your hip joint.


Feature 5: My lower back hurts when I sleep on my back.

A common complaint among people with lordosis (excessive curvature of the lower back) is that they experience lower back pain when sleeping on their backs.

A gap can easily form between your lower back and the floor, causing tension in your lower back even while you sleep.

Therefore,

  • When I lie on my back, my lower back feels like it's floating.
  • Lying on your side is more comfortable
  • I feel heavy when I wake up in the morning.

This situation is more likely to occur.


Feature 6: My lower back gets tired easily when I stand.

People with an arched lower back are prone to putting strain on their lower back even when just standing.

especially,

  • Standing in the kitchen is tough.
  • Standing on the train makes my lower back hurt.
  • Standing for long periods of time is tiring.

If this sounds like you, you might be supporting yourself solely with your lower back.


An exaggerated lumbar curve is not just a problem of the lower back.

When we talk about lordosis, we tend to think of it as a "back problem," but in reality

  • pelvis
  • hip joint
  • stomach
  • Buttocks
  • Front of the thigh
  • back

This involves the overall balance of the body.

Therefore, simply massaging the lower back may not bring about fundamental changes.


Re-Set examines the balance of the entire body.

At Hashimoto's chiropractic salon, Re・Set, we treat lordosis not only by focusing on the lower back, but also by considering the balance of the entire body.

especially,

  • Pelvic tilt
  • Stiffness in the front of the hip joint
  • How to use your stomach and buttocks
  • Thigh tightness
  • Posture habits
  • Shallow breathing

We will adjust the arrangements to suit each individual, taking these factors into consideration.

"I'm worried about my lordosis (swayback)."
"My lower back gets tired easily."
"I'm worried about my protruding belly."
"My lower back hurts when I sleep on my back."

If that sounds like you, why not take a look at your body's balance?
