The difference between rickets and pigeon chest: Pigeon chest is a symptom of rickets; rickets is mainly caused by a lack of vitamin D and calcium, leading to disorders in calcium and phosphorus metabolism. During the acute phase of rickets, when skeletal changes occur, this condition can easily cause deformities in the patient's chest. The pigeon chest deformity is one of the symptoms of rickets. That is to say, pigeon chest is a symptom of rickets, not a disease itself.

The difference between rib flare and pigeon chest

The main difference between rib flaring and pigeon chest is that the former is caused by soft tissue pathology around the thoracic cage, while the latter is due to a bony deformity of the thoracic cage. Patients with rib flaring often have very thin muscles around the thoracic cage due to poor posture, such as excessive abdominal tucking or long-term dieting, which leads to a very prominent thoracic cage when standing. Pigeon chest, on the other hand, is due to severe malnutrition during the patient's growth and development phase, which leads to the anteroposterior diameter of the thoracic cage being larger relative to the mediolateral diameter. In this case, the patient will exhibit a noticeably protruding thoracic cage, especially at the front.

Can eating chicken breast help with weight loss?

During weight loss, if liver and kidney functions are normal, we can recommend a high-protein diet to our patients. This type of diet is characterized by a noticeable weight loss effect. In the high-protein diet, it is required that patients should opt for high-protein foods more frequently and whey protein can be added if necessary. Among high-protein foods, we recommend that patients use skinless chicken breast because it is rich in leucine, which is beneficial for fat reduction and muscle gain, thus it should be chosen more often during weight loss. During weight loss, it is also important to ensure a balanced diet and variety in food choices. We also suggest that patients can incorporate whole grains, skim milk, boiled eggs, lean beef, steamed fish, beans and their products, fresh green leafy vegetables, and low-sugar fruits, among others. Additionally, forming a good habit of exercising is essential to maintain an ideal weight.

How to correct pigeon chest in children

Treatment should be decided based on the specific condition of the child's pigeon chest. For mild to moderate pigeon chest, especially in children, where there is no compression on the heart and lungs, conservative treatment should generally be considered. The best method for correction is to pay attention to posture and engage in appropriate physical exercise. Additionally, a thoracic orthotic can be used; the effects of wearing a thoracic orthotic for correcting mild to moderate pigeon chest are generally quite positive. For severe pigeon chest, particularly when there is compression affecting the heart and lungs and thus impacting cardiac and pulmonary function, surgical treatment should be considered to correct the severe pigeon chest.

How to determine if a baby has pigeon chest

Pectus carinatum, commonly referred to as pigeon chest, is a manifestation of the skeletal sequelae of rickets in children, where the sternum protrudes outward. To examine for pigeon chest, one commonly uses the hand to feel from top to bottom; if the sternum is noticeably protruding from the surface, then pigeon chest may be considered. This condition is a sequelae caused by a deficiency of Vitamin D. If this is the case, it is essential to visit a pediatric care, growth and development, or general pediatric outpatient clinic, where a pediatrician can confirm the diagnosis. If pigeon chest is confirmed, blood tests to measure Vitamin D levels should be conducted for infants. For older children, appropriate calcium supplementation and exercises to expand the chest should also be considered.

The differences between funnel chest and pigeon chest

Pectus excavatum and pectus carinatum are both types of chest wall deformities. Pectus excavatum is the most common form of chest wall deformity, accounting for over 90% of all anterior chest wall deformities, whereas pectus carinatum occurs much less frequently, roughly one-fifth the incidence of pectus excavatum. The main and most apparent difference is that, as the name suggests, pectus excavatum looks as if a funnel were placed in the chest, with the funnel pointing downwards and backwards. Thus, in patients or children with pectus excavatum, the sternum is indented inward and backward, pressing directly towards the spine. This indentation can compress the heart and lungs, potentially distorting and even displacing the heart to one side. In contrast, pectus carinatum involves the sternum protruding outward, resembling the chest of a chicken or a pigeon. Pectus excavatum is characterized by a backward indentation, while pectus carinatum protrudes forward—this is the most direct distinction.
