Physicians help their patients to diet by monitoring important statistics, such as weight, measurements, blood diagnostics, hormone levels, blood pressure, cholesterol levels, kidney functioning and heart health, according to Debra-Lynn B. Hook for Everyday Health. Doctors can help their patients tailor a specific diet to meet their needs and advise them when surgery or medication may be necessary.
Many people do not require the sole expertise of a physician when attempting a new diet, says Hook. Doctors often work together with other specialists to help their patients reach health goals. Registered dietitians are excellent resources when it comes to assessing a patient's objectives. Sometimes, a person can establish an improved regimen through the assistance of a dietitian and personal trainer without the need of a doctor. Many gyms offer these services with monthly enrollment.
Hook notes that some cases may require medical intervention, such as when a person is obese, suffering with heart or lung disease or diabetes, considering weight loss surgery or an extreme diet that may restrict calorie consumption to less than 1,000 calories per day, or taking medications that may need to be increased or decreased as the person's weight adjusts. This is also the case if the person has a family history of sudden death or heart disease.
