Heart Rate Changes
Eating disorders can significantly affect the heart. Malnutrition and dehydration may cause the heart rate to slow (bradycardia) or become irregular. In severe cases, this can increase the risk of dizziness, fainting, heart complications, or even cardiac arrest.
Electrolyte Imbalances
Electrolytes such as potassium, sodium, and magnesium are essential for proper nerve and muscle function. Purging behaviors, dehydration, and inadequate nutrition can disrupt these levels. This may lead to muscle weakness, dizziness, fainting, and dangerous heart rhythm abnormalities.
Bone Density Loss
Low nutritional intake and hormonal changes can reduce bone density over time. This can increase the risk of osteopenia or osteoporosis, making bones more fragile and more likely to fracture, even at a young age.
Hormonal Disruptions
Eating disorders often disrupt the body’s hormonal balance. These changes can affect metabolism, mood, growth, and reproductive health. For many individuals, this may lead to missed menstrual cycles, fertility challenges, and other long-term endocrine changes.
Amenorrhea (Loss of Period)
Amenorrhea means the loss of a menstrual period. Medical concerns typically begin after three months without menstruation, and it should always be evaluated by a healthcare provider.
Gastrointestinal Issues (Slowed Digestion)
Eating disorders can slow down the digestive system. This may lead to symptoms like bloating, constipation, stomach pain, and feeling full very quickly. These symptoms can be uncomfortable and may make it even harder for individuals to maintain regular eating patterns.
Hypoglycemia (Low Blood Sugar)
Not eating enough or going long periods without food can cause blood sugar levels to drop. This may lead to shakiness, dizziness, fatigue, irritability, and difficulty concentrating. In more severe cases, it can cause fainting or medical emergencies.
Lanugo (Fine Body Hair Growth)
When the body is not getting enough nutrition, it may try to protect itself by growing a fine, soft layer of hair called lanugo. This is the body’s way of helping to keep warm when body fat is too low. While it can be surprising to see, it is a sign that the body is struggling and needs proper nourishment
