Osteoporosis is a bone disease that affects men and women of all races, as losing bone is a normal part of ageing. However, especially white and Asian women in the first few years after the menopause are at the highest risk. But this bone disease can also affect younger women, men, and children.
Osteoporosis happens when your body makes too little bone or loses too much bone, or both, as bone is living tissue that is constantly being broken down and replaced. As a result, bones become weak and brittle and may break from a fall (1, 20).
However, a healthy diet, balanced lifestyle, exercise, and if needed – medications, may help prevent bone loss or strengthen already weak bones. Here are 7 tips to prevent osteoporosis.
Osteoporosis Signs and Symptoms
Typically there are no signs and symptoms in the early stages of osteoporosis. Therefore, your best bet for detecting osteoporosis in the early stages is going to the doctor. However, once your bones have been weakened by osteoporosis, you might have some signs and symptoms that can indicate bone loss:
Early stage osteoporosis signs and symptoms
- Receding gums. If your jaw is losing bone, your gums may move back (recede).
- Weaker grip strength. In one study researchers found that low handgrip strength was linked to low bone mineral density.
- Weak and brittle fingernails. Nail strength may also indicate the health of your bones. However, nails may be brittle also because of other reasons such as for example some artwork, swimming or gardening (2, 3).
Later-stage osteoporosis signs and symptoms
- Back pain, or neck pain. Osteoporosis may lead to compression fractures of the spine which can be from minor to extremely painful, as the collapsed vertebrae may pinch the nerves that radiate out from the spinal cord.
- A stooped posture or compression fracture. The compression of the small bones that form the spine (vertebrae) may also cause a small curving of the upper back.
- A stooped back, also known as kyphosis can cause back and neck pain and even affect breathing due to extra pressure on the airway and limited expansion of your lungs.
- Loss of height over time. This is one of the most visible symptoms of osteoporosis, because these compression fractures in the spine may also lead to a loss of height.
- A bone that breaks extremely easily. Fractures may happen even with a minor movement or fall (1, 2, 3).
Osteopenia – Bone Loss Before Osteoporosis
Osteopenia is a stage before osteoporosis, when a bone density scan shows you have lower bone density than the average for your age, but not low enough to be diagnosed as osteoporosis.
However, osteopenia does not always lead to osteoporosis, and there are steps you can take in addition to calcium and vitamin D rich diet (such as one of the bone-strengthening treatments) to reduce your risk of developing osteoporosis and keep your bones healthy (4).
Osteoporosis Causes, Risk Factors and Risk Groups
Although men and women both can get osteoporosis, this health condition is more typical in women, as it’s mostly caused by hormonal shifts that happen with aging. Osteoporosis occurs when the body breaks down your bone tissue quicker than it can create more (2).
Many factors may increase the risk of developing osteoporosis, for instance:
- A family history of osteoporosis
- A parental history of hip fracture
- Older age
- Low levels of calcium and vitamin D
- Being Caucasian or Asian. About a third of white and Asian men over age 50 have low bone density. The prevalence is lower among Hispanics (23%) and blacks (19%).
- Eating disorders such as anorexia or bulimia
- Not enough regular physical activity (especially strength-training exercise) or long periods of inactivity (such as long-term bed rest)
- Low body mass index (BMI) for example 19 or less
- Excess drinking and smoking
- In women, low oestrogen levels after the menopause may lead to a rapid decrease in bone density. Women are at even higher risk of developing osteoporosis if they have:
- menopause before the age of 45
- removal of the womb (a hysterectomy) before the age of 45
- removal of the ovaries before age 45
- absent periods for more than 6 months (for example due to overexercising or too much dieting)
- In men, low levels of testosterone
- Certain medical conditions such as:
- inflammatory conditions
- hormone-related conditions and a disorders of the hormone-producing glands, such as overactive thyroid gland, disorders of the adrenal glands, such as Cushing’s syndrome, decreased amounts of sex hormones (oestrogen and testosterone). Also disorders of the pituitary gland and overactivity of the parathyroid glands
- malabsorption problems
- coeliac disease and Crohn’s disease
- rheumatoid arthritis
- kidney failure
- multiple sclerosis
- The use of certain medicines like as for example:
- medicines for breast cancer and prostate cancer treatment
- medications that decrease hormone levels
- using high-dose steroid pills for long time (used to treat conditions such as arthritis and asthma)
- taking immunosuppressive medications and steroids, like prednisone
- seizure medications and thyroid replacement therapy (if dosage is too high) (1, 2, 4, 5, 6, 21).
Osteoporosis Prevention – 8 Ways to Prevent Osteoporosis
Although mostly your genes are responsible for determining your height and the strength of your skeleton, lifestyle factors such as diet and exercise also influence how healthy your bones are. Here are some tips to keep your bones in good shape (1, 4).
1. Exercising regularly, as regular exercise is vital for healthy bones
- Aerobic activities. Individuals aged 19 to 64 should do at least 2 hours and 30 minutes of moderate-intensity aerobic activity each week. For example cycling, fast walking, or swimming
- Weight-bearing exercises (also resistance exercise) where your feet and legs support your weight are particularly important for improving bone density and helping to prevent osteoporosis. Individuals over the age of 60 may also benefit from regular weight-bearing exercise. Weight-bearing exercises include for example brisk walking, keep-fit classes or tennis, but not swimming and cycling.
- High-impact weight-bearing exercises are extremely vital for strengthening your muscles, joints and ligaments. These exercises are for example aerobics, dancing, hiking, running, skipping, stair climbing and even jumping up and down on the spot.
- Muscle-strengthening activities. Individuals aged 19 to 64 should also do muscle-strengthening activities on 2 or more days a week by working all the major muscle groups, including the legs, hips, back, abdomen, chest, arms and shoulders.
- Resistance exercises. These exercises use muscle strength and boosts bone strength, as the action of the tendons pulling on the bones. Examples include press-ups, weightlifting or using weight equipment at a gym (1, 4).
Calcium is important for maintaining strong bones. According to Mayo Clinic, all adults between the ages of 18 and 50 need 1,000 milligrams of calcium a day, which you should be able to get from your daily diet. However, this daily amount increases to 1,200 milligrams when women turn 50 and men turn 70 (1).
Calcium-rich foods include for example:
- Green leafy vegetables like for example spinach, kale, turnips
- Dried fruit
- Canned salmon or sardines with bones
- Fortified cereals
- Fortified orange juice
- Soybeans and fortified soymilk
- In addition, enriched breads, grains, and waffles (1, 4, 7).
Even though the evidence is still fragmented, most of the data accessible point to Magnesium as a benefactor element to bone health. Magnesium deficiency is linked to osteoporosis, as it acts on crystal formation and on bone cells. Magnesium also impacts on the secretion and the activity of parathyroid hormone and promotes low grade inflammation.
Therefore, optimizing magnesium intake might represent an effective and low-cost preventive measure against osteoporosis in individuals with magnesium deficiency.
Magnesium rich foods are for example:
- Fish like Chinook salmon, halibut, mackerel or pollock
- Swiss chard
- Potato with skin
- Black-eyed peas (cooked)
- Tempeh (cooked)
- Soy nuts
- Cooked beans (black, lima, navy, pinto, chickpeas)
- Peanut butter
- In addition, mineral or mineralized water (17).
4. Vitamin K-2
There is some limited evidence that also certain other supplements, such as vitamin K-2 and soy, may help lower fracture risk in case osteoporosis. However more studies are needed to prove these health benefits and determine risks (25).
5. Vitamin D
Vitamin D is vital for healthy bones because together with calcium, optimal amounts of vitamin D may help support bone health, prevent osteomalacia (softening of the bones due to a disorder of bone mineralization) and osteoporosis (thinning of the bone) ( 8, 9, 10, 11, 12, 13, 14).
According to Mayo Clinic, to get enough vitamin D to maintain bone health, it’s suggested that all adults (aged 51 to 70) get 600 IU daily, and older adults (after the age 70) 800 IU a day through food or dietary supplements.
Vitamin D-rich foods include:
- Cod liver oil: 34.0 mcg (1,360 IU)/1 tbsp – 170% DV
- Trout (rainbow), farmed, cooked: 16.2 mcg (645 IU)/3oz – 81% DV
- Salmon (sockeye), cooked: 14.2 mcg (570 IU)/3 oz – 71% DV
- Mushrooms, white, raw, sliced, exposed to UV light: 9.2 mcg (366 IU)/ ½ cup – 46% DV
- Milk, 2% milkfat, vitamin D fortified: 2.9 mcg (120 IU)/1 cup – 15% DV
- Soy, almond, and oat milks, vitamin D fortified, various brands: 2.5-3.6 mcg (100-144 IU)/1 cup – 13-18% DV
- Ready-to-eat cereal, fortified with vitamin D: 2.0 mcg (80 IU)/1 serving – 10% DV
- Sardines (Atlantic), canned in oil, drained: 1.2 mcg (46 IU)/2 sardines – 6% DV
- Egg, scrambled**: 1.1 mcg (44 IU)/1 large – 6% DV
- Liver, beef, braised: 1.0 mcg (42 IU)/3 oz – 5% DV
- Tuna fish (light), canned in water, drained: 1.0 mcg (40 IU)/ 3 oz – 5% DV
- Cheese, cheddar: 0.3 mcg (12 IU)/1 oz – 2% DV
- Mushrooms, portabella, raw, diced: 0.1 mcg (4 IU)/½ cup – 1% DV
- Chicken breast, roasted: 0.1 mcg (4 IU)/3 oz 1% DV
- Beef, ground, 90% lean, broiled: 0 mcg (1.7 IU)/3 oz – 0% DV (15).
- mcg (μg) – Micrograms per serving
- IU – International Units per serving
- DV – Percent Daily Value
- oz – ounces
- ** Only egg yolk contains vitamin D
- 1 mcg (μg) of vitamin D is equivalent to 40 IU
6. Normal weight
Low body weight, especially BMI (Body Mass Index) 19 or less, has been associated with an increased risk of osteoporosis, as it raises the chance of bone loss and fractures. However, excess weight isn’t beneficial also, as it’s known now to increase the risk of fractures in your arm and wrist. Therefore, maintaining a suitable balance in your body weight is beneficial for your bones and for your overall health as a whole (1).
7. Quit smoking and drink in moderation
- Consistent drinking of more than two alcoholic beverages a day may increase your risk of osteoporosis. Therefore, the NHS recommends not to drink more than 14 units of alcohol a week. Also, it’s vital to avoid binge drinking (1, 4).
- The exact reason why tobacco plays a role in osteoporosis isn’t totally clear yet, however, smoking is associated with an increased risk of weak bones and osteoporosis (1, 4).
8. Smile to sun
Vitamin D (D3 – cholecalciferol) is produced in the skin from 7-dehydrocholesterol by the sun (or ultraviolet light UV) with an UV index of 3 or more. Therefore, to maintain healthy vitamin D levels in your body, which helps your body absorb calcium, you should aim to get 10–30 minutes of midday sunlight, several times per week.
However, people with darker skin may need a little more than this (4, 18, 19). As nowadays people stay and work more indoors, the vitamin D deficiency is very common. Therefore, to obtain sufficient amounts of vitamin D you can eat more vitamin D rich foods or take vitamin D supplements, as low vitamin D levels might contribute to osteoporosis.
However, do not start to self medicate and consult your doctor if you suspect osteopenia or osteoporosis. Your doctor will then make the necessary tests such as for example bone density tests, and suggests the treatment.
Diagnosing Osteopenia and Osteoporosis – The Bone Density Test
Although there are also other methods, the main way to determine your bone density is to have a dual-energy x-ray absorptiometry (also called DXA or DEXA) test that is painless, noninvasive and measures the mineral content of bone. In short, the test shows which category – normal, osteopenia, or osteoporosis – a person falls into compared to a normal 30 year old person of the same sex and age (21, 22, 23, 24).
How to read the results of the bone density test
- -1 and above: Normal
- Between -1 and -2.5: A sign of osteopenia
- -2.5 and below: You likely have osteoporosis
After using information such as the bone density test, the treatment suggestions are usually based on an estimate of your risk of breaking a bone in the next 10 years. However, if the risk isn’t high, the treatment might mostly concern on adjusting risk factors for bone loss and falls, and might not include medication (1).
- Focusing on modifying osteoporosis risk factors.
- Bisphosphonates. These are the most widely prescribed osteoporosis for both men and women at increased risk of fracture. Examples include:
- Alendronate (Binosto, Fosamax)
- Risedronate (Actonel, Atelvia)
- Ibandronate (Boniva)
- Zoledronic acid (Reclast, Zometa)
- Monoclonal antibody medications.
- Hormone-related therapy:
- Estrogen may help maintain bone density in women.
- Testosterone replacement therapy in men, because osteoporosis might be linked with an age-related decline in testosterone levels.
- Bone-building medications. Your doctor may recommend bone-building medications if common treatments don’t work well enough or you can’t tolerate these. Bone-building medications include:
- Teriparatide (Forteo)
- Abaloparatide (Tymlos)
- Romosozumab (Evenity)(1).
