Physical therapy and nutrition are often seen as separate, but the truth is, they are deeply
intertwined. To get the most out of PT, especially after an injury or surgery, integrating both is
crucial. Here’s why:
Food Fuels The Body
During recovery from an injury or surgery, your body is working to heal itself. The activities and
exercises you’re doing in PT are designed to help it along. To take advantage of all the work
you and your body are putting in, proper nutrition is critical.
Protein provides the building blocks for tissue repair and muscle growth. Carbohydrates provide
energy and help support your immune system. Your body also needs healthy fats to regulate
inflammation and to build certain cells. Being short on any of these critical components will slow
your recovery down.
You also need enough micronutrients, like vitamins and minerals. For example, vitamin C is
needed to make collagen, which goes into bones, skin, and connective tissue. Vitamin D helps
your body absorb calcium, which is important for healing fractures, or surgeries involving bones.
Iron helps your blood cells carry oxygen throughout your body, which is needed for healing in
general. Again, being low on any of these micronutrients will affect your healing.
Your Weight Affects Your Health
Being overweight directly affects your health. It puts you at higher risk for cardiovascular
disease, stroke, osteoarthritis, back pain, diabetes, sleep apnea, and more. All of these are
conditions that you might see a PT directly for, or that will impact your healing. Eating a healthy
diet is the most effective way to reduce body weight. Combining a healthy diet with exercise is
even better for your health.
As an example, an 18-month study of 450 people with knee osteoarthritis showed that the group
that lost weight through a diet and exercised had less pain, better walking speed, and lower joint
forces in their knees than groups who either only lost weight, or only exercised.
How can a physical therapist help with nutrition?
While PTs are not authorized to provide individual diet plans or medical nutritional advice, they
can still help with your nutrition.
• PTs can screen for potential nutritional deficiencies or imbalances that may impact your
progress in PT or your overall health. This might involve screening for malnutrition,
sarcopenia (muscle loss), or assessing dietary habits affecting energy levels, healing, or
muscle building.
• Your PT can educate you on the importance of nutrition for various aspects of
rehabilitation and recovery. This includes explaining how specific nutrients like protein,
vitamins, and minerals contribute to tissue repair, muscle building, energy production,
and pain management.
• They can offer general guidance on healthy eating patterns, portion control, and
choosing nutrient-rich foods to support reaching your specific physical therapy goals.
• PTs recognize that overall health and well-being involve various factors, including proper
nutrition. They can encourage you to adopt healthy lifestyle habits that include a
balanced diet alongside regular exercise and proper sleep hygiene.
Finally, your PT can recognize when your nutrition needs exceed what they are able to provide.
In that case, they can refer you to and collaborate with a registered dietician or other qualified
healthcare professional for help in dealing with complex nutritional needs or recommending
specific dietary changes.
By combining the power of physical therapy and nutrition, you can achieve your
recovery goals faster and feel your best!
