Diet pills, also known as appetite suppressants, are a type of weight-loss medication that can help people with obesity lose weight by reducing their appetite or making them feel full faster. While these pills can be effective for weight loss, they may also cause various side effects, including mood changes and swings. Federal regulators have warned that many marketed dietary supplements can be ineffective and may even cause severe side effects. It is important to consult a healthcare provider before taking any diet pills to ensure safe usage and avoid potential health risks. While the exact link between diet pills and mood swings requires further research, there are reports of psychiatric side effects, including mood changes, depression, mania, psychosis, hallucinations, and paranoia. Additionally, diet pills can affect neurotransmitters in the brain, leading to headaches, dry mouth, dizziness, and stomach issues. Stimulant-type diet pills can also lead to insomnia, increased blood pressure, restlessness, and drug dependence.

What You'll Learn
Diet pills and serotonin loss
Diet pills, also known as appetite suppressants, are a type of weight-loss medication for people with obesity. They work by lessening appetite or making one feel full faster. While they can be beneficial, they may also have adverse effects when interacting with other medications.
Serotonin syndrome is a condition that occurs due to an excessive accumulation of serotonin in the body. Serotonin is a chemical that helps regulate attention, behaviour, body temperature, digestive processes, blood flow, and breathing. It is produced by nerve cells in the brain and spinal cord, and other nerve cells in the body, primarily in the intestines. Serotonin syndrome can be caused by certain medications, most often by combining medications that contain serotonin. This includes prescription and over-the-counter drugs, herbal or dietary supplements, and illegal drugs. Dietary supplements that can cause serotonin syndrome include St. John's wort, ginseng, Syrian rue, nutmeg, and tryptophan. Recreational drugs such as LSD, cocaine, ecstasy, amphetamines, fentanyl, and methamphetamines can also lead to serotonin syndrome when combined with antidepressants.
Symptoms of serotonin syndrome can range from mild, such as diarrhea or nausea, to severe, such as high fever or seizures. They usually occur within several hours of taking a new drug or increasing the dose. In severe cases, serotonin syndrome can be life-threatening and requires immediate medical attention.
While diet pills themselves may not directly cause serotonin loss, they can interact with other medications and increase the risk of serotonin syndrome. It is important to consult a healthcare provider before taking diet pills, especially if one is already taking medications that affect serotonin levels.
Additionally, diet pills can cause various side effects, including mood changes, cognitive (mental) changes, nausea, vomiting, diarrhea, constipation, abdominal pain, insomnia, increased blood pressure, fast heart rate, restlessness, drug dependence, and withdrawal symptoms. Some diet pills have also been associated with serious psychiatric side effects, such as depression, mania, psychosis, hallucinations, paranoia, delusions, and thoughts of suicide.

Bupropion and naltrexone side effects
Diet pills can cause mood swings, and this can be a significant obstacle to losing weight. Dieting can cause hormone and blood sugar levels to fluctuate, resulting in mood and energy swings. Mood changes, such as depression or anxiety, are also listed as side effects of appetite suppressants.
Bupropion and naltrexone is a combination medicine used to help manage weight in obese or overweight adults with weight-related medical problems. Bupropion is an antidepressant medicine that can also decrease appetite, while naltrexone is usually given to block the effects of opioids or alcohol in people with addiction problems. It may also curb hunger and food cravings.
The following are common side effects of bupropion and naltrexone:
- Nausea
- Constipation
- Headache
- Vomiting
- Dizziness
- Insomnia
- Dry mouth
- Diarrhea
- Tremor
- Hot flush
- Tinnitus
- Upper abdominal pain
- Hyperhidrosis
More serious side effects include:
- High blood pressure
- Seizures
- Suicidal thoughts or behaviour
- Cholecystitis/cholelithiasis
- Depression-related events
- Myocardial infarction
It is important to note that bupropion and naltrexone may not be safe to use in combination with certain medications, such as opioid medication, methadone, heroin, or other street drugs. Doing so could result in dangerous effects, including coma and death. Therefore, it is crucial to consult a healthcare provider before taking any diet pills or appetite suppressants to ensure safe and effective use.

Phentermine and psychosis
Phentermine is a controlled substance with a high dopamine potency that is often prescribed for weight loss. It is known to cause insomnia, increased blood pressure, a fast heart rate, restlessness, drug dependence, abuse, and withdrawal symptoms.
While the exact mechanism of phentermine causing psychosis is unclear, several reports have shown that it can induce psychosis. A case study involving a 25-year-old Asian female patient who developed psychotic symptoms repeatedly after taking phentermine suggests that phentermine can cause recurrent psychotic episodes, resulting in chronic occupational and social impairment. Another case study involving a 40-year-old White mother of four with bipolar II disorder and morbid obesity who was prescribed phentermine also experienced a hypomanic episode with symptoms such as euphoric mood, low sleep, pressured speech, high energy, racing thoughts, irritability, disinhibition, elevated libido, and unsafe sexual practices.
Phentermine is also known to worsen psychosis or bipolar disorder when taken alone or in combination with antidepressants. It can cause neuropsychiatric symptoms, including insomnia, mood swings, anxiety, panic attacks, irritability, increased anger, agitation, and secondary parkinsonism. Taking phentermine with antidepressants like venlafaxine or fluoxetine can cause severe neuropsychiatric complications. Phentermine overuse can cause reversible psychosis in young patients with no prior psychiatric illness.
It is important to consult a healthcare provider before taking phentermine or other diet pills, as they may have severe side effects and addiction potential.

Fenfluramine and brain damage
Diet pills can cause mood swings due to a variety of factors, including hormone and blood sugar fluctuations, lifestyle adjustments, and the ingredients in the pills themselves. While some people may experience mood swings when dieting due to factors such as a perceived lack of progress or frustration with slow weight loss, diet pills can also play a role.
Some diet pills contain stimulants like phentermine (Adipex-P), which can lead to insomnia, increased blood pressure, a fast heart rate, restlessness, and drug dependence, all of which can contribute to mood swings. Other diet pills, such as those containing bupropion and naltrexone (Contrave), can cause headaches, dry mouth, dizziness, and stomach issues like nausea, vomiting, and constipation. These physical side effects can also impact an individual's mood and energy levels.
Additionally, certain ingredients in diet pills have been linked to more serious psychiatric side effects, including mood changes, depression, mania, psychosis, hallucinations, paranoia, and delusions. For example, sibutramine was withdrawn from the U.S. market in 2010 due to safety concerns, and the stimulant ephedra was removed from dietary products due to severe side effects such as heart attacks, strokes, and seizures.
One particular ingredient in diet pills that has raised concerns about brain damage is fenfluramine. Animal studies have shown that fenfluramine and its chemical cousin dexfenfluramine can cause brain serotonin neurotoxicity, leading to permanent damage to serotonin-secreting neurons. While human studies have not been conducted, researchers caution that if the findings from animal studies apply to humans, brain damage would be expected to occur in most individuals taking a dose sufficient for weight loss.
The potential for brain damage from fenfluramine is a serious concern, as serotonin plays a crucial role in regulating mood, anxiety, cognitive function, and impulse control. Users of diet pills containing fenfluramine may suffer from an irreversible loss of brain serotonin nerve terminals, resulting in symptoms of anxiety, depression, cognitive issues, and sleep problems. Therefore, doctors should be vigilant for behavioral and cardiopulmonary side effects and ensure that patients are informed of the risks and benefits of fenfluramine for weight loss.

Diet pills and blood sugar
Dietary supplements and medications can influence blood sugar levels, which is particularly important for individuals with diabetes. Diabetes is a disease characterised by high blood sugar levels, which, if left untreated, can lead to health complications such as heart disease, nerve damage, eye problems, and kidney disease.
Several supplements have been studied for their potential to lower blood sugar levels. Cinnamon, for instance, has been found to help lower blood sugar and improve diabetes control. Similarly, ginseng may help decrease post-meal blood sugar levels in healthy individuals and those with type 2 diabetes. Probiotic supplements, which contain beneficial bacteria, may also improve the body's handling of carbohydrates. Additionally, magnesium supplements have been linked to improved insulin sensitivity and better blood sugar control. However, excessive magnesium intake should be avoided unless recommended by a healthcare provider.
Some dietary supplements, such as berberine, chromium, and alpha-lipoic acid, have shown mixed results in terms of their effectiveness in lowering blood sugar. While berberine has been found to reduce fasting blood sugar without causing hypoglycaemia, it may cause digestive issues such as constipation, diarrhoea, or gas. Alpha-lipoic acid has been studied for its potential to improve blood sugar levels in people with diabetes, but one review found it to be no better than a placebo.
In terms of medications, there are various options available to help manage blood sugar levels, particularly for individuals with type 2 diabetes. Oral medications, such as metformin, work by decreasing glucose production in the liver and improving insulin sensitivity in muscle tissue. Injectable medications, such as GLP-1 receptor agonists like semaglutide, also help to lower blood sugar levels. Additionally, DPP-4 inhibitors improve long-term blood glucose control without causing hypoglycaemia.
It is important to note that supplements should not replace prescribed medications for managing blood sugar or diabetes. Combining certain medications with specific supplements may lead to interactions, so it is crucial to consult a healthcare professional before taking any supplements, especially when managing a health condition.
