Some issues Dr. David Arthur Merrill, MD can help you with:

Bulimia

Acid reflux
Intestinal distress
Dehydration from purging
Amenorrhea (the absence of menstruation)
Dental erosion from vomiting
Stomach ulcers
Delayed stomach emptying

Some people with bulimia may have swollen parotid glands (salivary glands near the cheeks) that give their face a puffy "chipmunk" appearance. Their skin may look dehydrated and dull from repeated purging. Red scars and marks on the backs of the knuckles are prevalent in those with bulimia. Eating disorder experts may refer to these as "Russel's sign," named after a well-known psychologist.

However, others with bulimia may not show any outward signs of having an eating disorder. They may deliberately hide their eating habits or conceal their purging after a meal. It is important that family members and friends help loved ones with bulimia seek treatment. While many people with bulimia are still able to lead outwardly successful and active lifestyles, bulimia may have lasting and severe consequences to one's health. Electrolyte imbalance from bulimia is particularly dangerous and may lead to heart attack or stroke. Similarly, continued dehydration and disturbances in electrolyte levels can cause kidney damage and reduced kidney function.

Treatment for bulimia typically includes therapy and nutrition counseling. Eating disorder support groups, both online and in person, are often beneficial to recovery. Medical professionals may also look to treat the mental health problems that frequently accompany bulimia, which are body dysmorphia, post-traumatic stress disorder (PTSD), and depression. Dietary specialists can assist patients with reintegrating foods into their diet and increasing consumed calories. Some patients may attend inpatient rehabilitation or eating disorder clinics, which provide all of the above treatments in a residential facility.

Fortunately, many people recover from bulimia and are able to fully restore their health.

Depression

Everyone knows what it feels like to get the blues once in a while. But depression is a serious illness that is more severe than a bad day and lasts much longer. Symptoms of depression stop a person from being able to function and enjoy daily activities for weeks or months at a time. It can happen to anyone, and it isn't something that people can control by force of will or "snap out of it."

Some common symptoms of depression include:

Feeling sad, guilty, empty or hopeless
Fatigue and a lack of energy and motivation
A loss of pleasure in activities that were previously enjoyed
Unusual sleep or eating habits
Mental fog -- trouble concentrating, remembering, or making decisions
Physical aches and pains
Suicidal thoughts or a preoccupation with death

We don't yet know what causes depression, but it's thought that it is a combination of genetic, biological, environmental, and social influences. Because of this, the most effective treatments for depression combine medication with psychotherapy. Therapy, especially cognitive-behavioral therapy, can be extremely helpful in resolving the negative thoughts and feelings that come with depression. It gives patients new tools that they can use themselves to cope when their depression is making them feel down.

Some of the common medications used to treat depression include antidepressants such as SSRI's (Prozac, Paxil, Zoloft) or atypical antidepressants (Cymbalta, Wellbutrin). It's important to remember that these medications have different effects on everybody, and no one medication works right for everyone. Patients may have to try a couple before finding the one that works just right for them. If the first medication they try doesn't work, they should talk to their doctor about trying something else. In extreme cases where medication is not enough, electro-convulsive therapy and hospitalization may be the answer to keeping a severely depressed person safe.

Depression is a difficult illness to deal with, but it is more common than believed and there are many people who can help. With the right treatment, individuals with depression can get back to fully enjoying life again.

Eating Disorders

Eating disorders are mental and physical illnesses that impact behavior, emotions, and thoughts about eating, food, body appearance, and weight. These disorders are characterized by preoccupations with food and physical size, resulting in dramatic lifestyle changes and adverse health effects. In the past, eating disorders were often diagnosed using BMI (body mass index), or by assessing someone's weight. Eating disorders specialists now recognize that eating disorders may occur in people of all sizes. The most common eating disorders are anorexia nervosa, bulimia nervosa, and binge-eating disorder (BED).

Anorexia nervosa, frequently referred to as anorexia, is a disorder where people severely restrict the types and quantity of food they eat. Those with anorexia have an extreme fear of eating and gaining weight and may repeatedly weigh themselves or engage in harmful behaviors such as excessive exercise or starvation. Those with anorexia often find themselves preoccupied with food, but unable to consume a healthy amount of it. This results in symptoms such as abnormally low BMI, vitamin deficiency, fatigue, fainting, and amenorrhea (lack of menstruation in women). Anorexia may cause bluish discoloration of the hands, brittle and falling out hair, yellowish skin, and lanugo (fine, downy hair). Left untreated, anorexia can lead to organ failure, brain damage, and even death.

Bulimia nervosa, typically called bulimia, is a disorder where people binge (eat large quantities of food) and purge the food that they just consumed by vomiting, laxative abuse, fasting, or excessive exercise. This behavior is usually motivated by a feeling of powerlessness over eating and a fear of weight gain or desire for weight loss. Bulimia can occur in underweight, normal weight, and overweight people. Symptoms of bulimia include acid reflux, intestinal distress, dehydration from purging, amenorrhea, and dental erosion from vomiting. Some people with bulimia have swollen parotid glands (salivary glands near the cheeks) and red scars and marks on the backs of their knuckles. Electrolyte imbalance from bulimia can be particularly severe and may lead to heart attack or stroke.

Binge eating disorder (BED) is the most common eating disorder. People with BED feel that they are unable to control the amount of food they eat and may continue to binge after reaching a point of fullness. BED binges (consuming large amounts of food) are often accompanied by feelings of sadness, guilt, and shame. Symptoms of BED include obesity, acid reflux, weight gain, and dissatisfaction with one's body. People with BED tend to experience cycles of negative emotions and binges. Binges or BED episodes can be provoked by stress, boredom, restrictive dieting, depression, and other triggers.

Other common eating disorders include:

Pica, eating things that are not food, such as paper, ice, or soil
Avoidant/Restrictive Food Intake Disorder (ARFID), disinterest in eating and avoidance of food
Other Specified Feeding or Eating Disorder (OSFED), abnormal eating that does not fall under any disorder

Many people with eating disorders do not consciously develop them, and have difficulty seeking treatment. For this reason, it's important to detect and treat eating disorders as early as possible. Treatment for eating disorders can vary from therapy visits to inpatient treatment, depending on the disorder and its severity. Treatment aims to not only restore physical health and correct negative behaviors, but to also promote psychological well-being and self-confidence.

Biography

Dr. Merrill has worked for several decades with patients suffering the behavioral health sequelae of age-related neurodegenerative disorders such as Alzheimer's disease and Parkinson's disorder. His more recent clinical and research work have expanded to include patients with history of head trauma, tumor, and stroke. Through his early adoption of emerging clinical practice technologies, Dr. Merrill has developed a "precision holistics" approach that combines personalized genetic and biomarker data with the best evidenced-based treatments available for alleviating depression and cognitive dysfunction within the context of aging.
