People with ligamentous laxity are more likely to develop joint hypermobility syndrome.
NHS Inform:1 Joint hypermobility means that some or all of a person’s joints have an unusually large range of movement.
People with hypermobility are very supple. This means they’re able to move their limbs into positions others find impossible.
Some people also refer to this as having loose joints or being double-jointed.
Symptoms of joint hypermobility
Many people with hypermobile joints don’t have any problems. For some people the extra flexibility may be a benefit. For example ballet dancers or gymnasts.
But, some people with joint hypermobility can have symptoms like:
- pain and stiffness in the joints and muscles
- clicking joints
- joints that dislocate (come out of the correct position) easily
- fatigue (extreme tiredness)
- recurrent injuries – like sprains
- digestive problems – like constipation and irritable bowel syndrome (IBS)
- dizziness and fainting
- thin or stretchy skin
If you have these symptoms with hypermobility, this could be a sign of:
- hypermobile Ehlers Danlos Syndrome (hEDS)
- Hypermobility Spectrum Disorder (HSD)
A person with hEDS or HSD may also have some other symptoms related to stretchiness in the connective tissues throughout their body. The severity can differ from one person to another.
Digestive system problems
hEDS or HSD can cause symptoms that affect your digestive system. This is because the connective tissue within your digestive system is more stretchy. This makes squeezing food either more difficult or quicker causing a range of problems including:
- gastro-oesophageal reflux disease (GORD)
- gastroparesis – where the stomach has difficulty emptying its contents into the small bowel which can cause bloating and nausea
- constipation
- irritable bowel syndrome (IBS)
Postural orthostatic tachycardia syndrome (POTS)
hEDS or HSD can also cause abnormalities in the part of your nervous system that controls bodily functions you do not actively think about. These are things like your heart beating. This is known as your autonomic nervous system.
These abnormalities can cause problems when you stand up or sit in the same position for a while. Your blood pressure can drop to low levels, making you feel sick, dizzy and sweaty. You may also faint.
In some people, these abnormalities can lead to postural orthostatic tachycardia syndrome (POTS). POTS causes your pulse rate to increase rapidly within a few minutes of standing up. You may also experience:
- dizziness or fainting
- headaches
- tummy upsets
- sweating
- a sensation of anxiety
- purple puffy fingers and feet
- a pounding or fluttering heart beat (heart palpitations)
Other problems
People with hEDS or HSD may have other related conditions and further symptoms, including:
- stress incontinence – when urine leaks out when your bladder is under pressure
- hernias – where an internal part of the body, like an organ, pushes through a weakness in the muscle or surrounding tissue wall
- in women, pelvic organ prolapse – where the organs inside the pelvis slip down from their normal position
- varicose veins – swollen and enlarged veins, usually blue or dark purple
- flat feet – where the inner part of your feet (the arch) is not raised off the ground when you stand
- headaches
- drooping eyelids
- a tendency to bruise easily and develop stretch marks
- thin or stretchy skin
