Difficulty Standing: Why Getting Up or Staying Up Is Hard

Difficulty standing means trouble getting up from a chair or bed, or trouble staying upright once you are up. The usual reasons are weak hip and thigh muscles, painful knees or hips, dizziness when you stand (a blood pressure drop), and nerve or brain conditions such as Parkinson's disease or spinal stenosis. Sudden inability to stand, especially with weakness on one side, numbness or confusion, is an emergency.

Also called: Trouble standing up, unable to stand, difficulty rising from a chair, standing intolerance

At a glance

What it is
Trouble rising from sitting or lying, or trouble staying upright once standing.
Common causes
Thigh and hip muscle weakness, knee or hip arthritis, back pain and dizziness when rising.
Serious causes
Stroke, spinal cord compression, Guillain-Barré syndrome, severe infection or bleeding.
Key question
Is the problem strength, pain, balance or lightheadedness?
Treatment
Depends on cause: strength training, joint treatment, medicine review and fall prevention.

When to get help

Call 911 or go to the ER

  • Sudden inability to stand with weakness or numbness on one side, face droop or slurred speech (possible stroke)
  • Both legs suddenly weak with numbness in the groin or buttocks, or loss of bladder or bowel control (possible spinal cord or cauda equina compression)
  • Fainting on standing with black stools, vomiting blood or heavy bleeding
  • Unable to stand after a fall, especially with hip or groin pain (possible hip fracture)

See a doctor within a day or two

  • Leg weakness that is worsening over hours or days, especially rising up from the feet
  • New confusion, fever or not eating, with sudden difficulty standing in an older adult (often an infection)
  • Repeated lightheadedness or near-fainting each time you stand
  • Severe shoulder and hip stiffness in the morning in someone over 50

Book a routine appointment

  • Gradually needing to push up with your arms to stand from a chair
  • Knee or hip pain that makes rising difficult
  • Being unable to stand still for long because of back or leg pain that eases when you sit

Usually safe to manage at home

  • Brief lightheadedness after standing quickly when you are hot or have not drunk enough, which passes within seconds

What difficulty standing can mean

Standing up uses the strongest muscles in the body: the quadriceps (front of the thigh) and the gluteal (buttock) muscles. It also needs working knee and hip joints, a balance system, and blood pressure that adjusts within seconds as blood pools in the legs. A problem with any of these makes standing hard.

It helps to work out which of four patterns fits:

PatternWhat it feels likeLikely causes
WeaknessLegs feel too weak to push you up; you need your armsSarcopenia, deconditioning, muscle or nerve disease
PainRising hurts in the knees, hips or backOsteoarthritis, back problems, injury
DizzinessLightheaded, vision dims or you nearly faint on risingOrthostatic hypotension, dehydration, medicines, POTS
Balance or stiffnessSlow to start, unsteady, fall backwardParkinson's disease, neuropathy, inner ear disorders

Causes

Muscle weakness

  • Sarcopenia: age-related muscle loss. Sarcopenia speeds up after 60 and is worse with inactivity, illness and low protein intake. Struggling to stand from a chair without your arms is one of its key signs.
  • Deconditioning after a hospital stay or long bed rest. Older adults can lose a noticeable amount of leg strength within a week in bed.
  • Muscle diseases (myopathies): inflammatory myositis, statin-related muscle problems and thyroid or steroid-related weakness affect the hips and thighs first, so rising from a chair and climbing stairs become hard.
  • Low potassium or other electrolyte problems.

Joint and back pain

  • Osteoarthritis of the knees and hips causes pain and stiffness on rising, worse after sitting for a while.
  • Spinal stenosis narrows the spinal canal in the lower back. Standing and walking cause leg pain, numbness or heaviness that eases when sitting or leaning forward (on a shopping cart, for example).
  • Polymyalgia rheumatica causes severe morning stiffness and pain in the shoulders and hips in people over 50, making it hard to get out of bed or a chair.

Dizziness when standing

Orthostatic hypotension is a drop in blood pressure of at least 20 mmHg systolic within 3 minutes of standing. Causes include dehydration, blood pressure medicines, diuretics, medicines for prostate problems, Parkinson's disease, diabetes affecting the nerves and blood loss. People describe lightheadedness, dimmed vision, weakness and sometimes fainting.

POTS (postural orthostatic tachycardia syndrome) mainly affects younger women. The heart rate jumps by 30 beats a minute or more on standing, with lightheadedness, palpitations and fatigue, often making standing in lines or showers hard.

Nerve and brain conditions

  • Parkinson's disease: slowness, stiffness and difficulty getting out of chairs, plus a shuffling walk and tremor.
  • Peripheral neuropathy: reduced feeling in the feet makes standing still unsteady, especially in the dark or with eyes closed.
  • Spinal cord compression or stroke: sudden weakness of one or both legs.
  • Guillain-Barré syndrome: weakness that starts in the feet and rises over days, often after an infection.
  • Cerebellar disorders: a wide, unsteady stance and swaying.

Acute illness in older adults

In older people, a sudden loss of ability to stand is often the first sign of a urinary or chest infection, dehydration, low sodium, a medicine side effect or a heart problem. Doctors treat it as a warning sign rather than "just old age".

How doctors assess it

Expect questions about when it started, whether it is weakness, pain or dizziness, falls, medicines and other symptoms. Common checks:

  • lying and standing blood pressure and pulse
  • the sit-to-stand test: how many times you can stand from a chair in 30 seconds without your arms, or the time to do it 5 times
  • strength, reflexes, sensation and walking
  • examination of the hips, knees and spine

Tests may include blood tests (blood count, potassium, sodium, kidney and thyroid function, vitamin B12, creatine kinase for muscle damage, inflammation markers), an ECG, X-rays of painful joints, and MRI of the spine if nerve compression is suspected.

Treatment and what helps

  • Strength training: progressive leg exercises, such as repeated sit-to-stands, step-ups and squats to a chair, 2 to 3 times a week. Strength improves at any age, even in people in their 90s.
  • Physical therapy for a tailored program, gait training and walking aids.
  • Medicine review: reducing or changing blood pressure medicines, sedatives or diuretics that cause dizziness.
  • For dizziness on standing: rise in stages (sit on the edge of the bed for a minute first), clench your leg muscles before standing, drink enough fluids, and ask about compression stockings.
  • For arthritis pain: weight management, exercise, pain relief following the label dose (with care using NSAIDs if you have kidney or stomach problems), injections, and joint replacement in severe cases.
  • Home changes: higher, firm chairs with arms, a raised toilet seat, grab bars and a bed at the right height.

Frequently asked questions

Why do I have trouble standing up from a chair?

The commonest reason is weakness of the thigh and hip muscles from age, inactivity or illness. Knee or hip arthritis and back pain also make rising hard. If you need to push with your arms, a physical therapist can test your strength and set up exercises that usually help within weeks.

Why do my legs feel weak when I stand?

Legs that feel weak or give out on standing can be from a drop in blood pressure, especially if you also feel lightheaded. Spinal stenosis causes leg heaviness when standing that eases with sitting. True muscle or nerve weakness is present whether you are standing or not.

Why do I feel dizzy when I stand up?

Dizziness on standing usually means your blood pressure drops for a few seconds before your body adjusts. Dehydration, heat, blood pressure medicines and some conditions such as diabetes and Parkinson's disease make it worse. Fainting, frequent episodes or dizziness with chest pain need medical review.

When is being unable to stand an emergency?

Call 911 or your local emergency number if someone suddenly cannot stand and has weakness on one side, slurred speech, numbness in the groin, loss of bladder control, a possible hip fracture after a fall, or fainting with signs of bleeding.

Can exercise help difficulty standing?

Yes. Regular leg strengthening, such as sit-to-stand repetitions and step-ups, is the most effective treatment for age-related weakness. Balance exercises reduce falls. Start slowly, hold on to a stable surface, and ask a physical therapist for a program if you have pain or have fallen.
