Answer:
Becky probably has bulimia nervosa.
Explanation:
Bulimia nervosa is an eating disorder much like anorexia. This disorder is characterized by a situation where an individual is very concerned about his weight and for this reason restricts the amount of food he consumes. However, in certain situations this individual develops a binge eating, eating large amounts of food. These episodes leave the individual with great remorse because he believes he will gain weight. As a result, the individual adopts inappropriate practices so as not to gain weight. Among these practices can be cited: provoked vomiting, laxative ingestion, safe exercise practice, fasting for long hours, among others.
Becky usually takes laxative after eating a large amount of food, which indicates that she may have bulimia nervosa.
Answer:
Which Drugs Are Abused?
The most commonly used prescription drugs fall into three classes:
1. Opioids
Examples: oxycodone (OxyContin), hydrocodone (Vicodin), and meperidine (Demerol)
Medical uses: Opioids are used to treat pain or relieve coughs or diarrhea.
How they work: Opioids attach to opioid receptors in the central nervous system (the brain and the spinal cord), preventing the brain from receiving pain messages.
2. Central Nervous System (CNS) Depressants
Examples: phenobarbital (Luminal), diazepam (Valium), and alprazolam (Xanax)
Medical uses: CNS depressants are used to treat anxiety, tension, panic attacks, and sleep disorders.
How they work: CNS depressants slow down brain activity by increasing the activity of a neurotransmitter called GABA. The result is a drowsy or calming effect.
3. Stimulants
Examples: methylphenidate (Ritalin) and amphetamine/dextroamphetamine (Adderall)
Medical uses: Stimulants can be used to treat narcolepsy and ADHD.
How they work: Stimulants increase brain activity, resulting in greater alertness, attention, and energy.
