Overview

Premenstrual Dysphoric Disorder
Premenstrual dysphoric disorder (PMDD) is a severe cyclical condition in which emotional, behavioral, and physical symptoms occur during the premenstrual phase and substantially interfere with daily functioning, relationships, work, or other activities. Symptoms typically improve after menstruation begins. PMDD is more severe than typical premenstrual symptoms and commonly includes marked mood changes, irritability, depression, anxiety, difficulty concentrating, fatigue, sleep changes, and physical symptoms.
Hepatitis C
Hepatitis C is a liver infection caused by the hepatitis C virus. It is transmitted primarily through contact with infected blood. Many people have few or no symptoms at first, but persistent infection can cause liver inflammation and, over time, serious complications such as cirrhosis or liver cancer. Acute hepatitis C may cause fatigue, nausea, abdominal discomfort, dark urine, or yellowing of the skin and eyes, although many people have no obvious symptoms. Some infections clear without treatment, while others become chronic. Chronic hepatitis C can progressively damage the liver if it remains untreated.

Diagnosis

Premenstrual Dysphoric Disorder
Diagnosis is based on the timing, number, severity, and cyclical recurrence of symptoms across menstrual cycles and the degree to which they interfere with daily functioning. Prospective symptom tracking over multiple cycles is often used to document the pattern. Evaluation also considers other psychiatric, medical, and gynecological conditions that can cause similar symptoms. There is no single blood test that confirms PMDD.
Hepatitis C
Hepatitis C is diagnosed with blood tests. An antibody test can show whether a person has been exposed to the virus, while an HCV RNA test confirms whether active infection is present. Additional blood tests and liver assessment help evaluate liver health and the extent of disease. Testing generally begins with an HCV antibody blood test. If antibodies are detected, an HCV RNA test determines whether the virus is currently present. Further assessment may include liver enzyme tests, blood counts, fibrosis assessment, and imaging or other investigations when needed to evaluate liver damage and complications.

Prevention

Premenstrual Dysphoric Disorder
There is no guaranteed way to prevent PMDD because it is associated with individual sensitivity to normal hormonal fluctuations. Regular sleep, physical activity, balanced nutrition, and effective stress management may help reduce the impact of symptoms. Tracking menstrual cycles and symptoms can help identify patterns and support early assessment when emotional or physical symptoms repeatedly interfere with work, relationships, or other daily activities.
Hepatitis C
Hepatitis C can be prevented by avoiding contact with infected blood. Do not share needles, syringes, razors, or other items that may contain blood. Use properly sterilized medical and tattoo equipment and follow appropriate precautions when there is a risk of blood exposure. There is currently no widely available vaccine for hepatitis C. Prevention therefore depends on reducing blood exposure, using sterile injection and medical equipment, and ensuring appropriate infection-control practices. People with ongoing exposure risks should discuss testing and prevention strategies with a healthcare professional.

Risk Factors

Premenstrual Dysphoric Disorder
Risk may be increased by a personal or family history of mood disorders, previous significant premenstrual symptoms, and individual sensitivity to normal reproductive hormone changes. Some people may also have coexisting anxiety or depressive disorders. PMDD occurs in people who are biologically sensitive to cyclical hormonal changes, and symptoms may vary over different stages of reproductive life.
Hepatitis C
Risk factors include sharing needles or other injection equipment, receiving medical care with inadequately sterilized equipment, having a blood transfusion or organ transplant before modern screening was introduced, and other exposures to infected blood. Risk can also increase with certain sexual or occupational exposures. People who inject drugs or share injection equipment have an important risk of blood exposure. Other risks include accidental exposure to infected blood, nonsterile tattooing or piercing equipment, and certain healthcare exposures. People with previous transfusions or transplants before routine HCV screening may also have increased risk.
