As an addiction psychiatry specialist, Dr. Kimathi Kigatiira focuses on helping patients overcome substance use disorders and addictive behaviors. Addiction is a complex condition that affects both the mind and body, and it often impacts relationships and daily functioning. With his specialized training, Dr. Kigatiira addresses both the psychological and physical aspects of addiction. He has extensive experience treating alcoholism and drug addiction, and he tailors treatment plans to each patient’s unique needs. Dr. Kigatiira understands that recovery from addiction is a journey involving medical treatment, counseling, and strong support systems. He works closely with patients and their families through every step of the recovery process — from detoxification and withdrawal management to therapy and long-term relapse prevention. Using evidence-based methods (including medication-assisted treatment when appropriate and therapies like cognitive-behavioral therapy), he provides patients with the tools and support needed to break free from addiction and rebuild their lives. In a community where substance abuse is a growing concern, Dr. Kigatiira’s expertise in addiction offers much-needed hope and professional guidance to those affected.Comprehensive Psychiatric Services Offered
Beyond addiction treatment, Dr. Kimathi Kigatiira provides a wide range of psychiatric services for individuals of all ages. He is dedicated to helping patients with various mental health conditions, ensuring each person receives the care suited to their situation. Below are some of the key services and treatments he offers:Addiction Treatment and Rehabilitation
One of Dr. Kigatiira’s primary services is addiction treatment and rehabilitation for individuals struggling with alcohol or drug dependency. His programs help patients safely quit addictive substances and maintain long-term recovery. Depending on each patient’s needs, the treatment plan may include supervised detoxification to manage withdrawal symptoms safely, regular counseling and psychotherapy to address underlying issues and teach coping strategies, and medication-assisted treatment (using medicines that reduce cravings or treat co-occurring mental health issues). In addition, Dr. Kigatiira strongly emphasizes family support in the recovery process. He often involves family members in therapy or educational sessions so they can actively support their loved one’s journey to sobriety. After the initial rehabilitation phase, he provides thorough aftercare planning — scheduling follow-up visits and connecting patients with support groups — to help individuals stay on track and prevent relapse. By addressing the root causes of addiction and providing continuous support, Dr. Kigatiira helps patients reclaim their lives from substance abuse.Anxiety Disorders Treatment
Dealing with an anxiety disorder can be overwhelming, but effective help is available. Dr. Kigatiira treats anxiety disorders such as generalized anxiety disorder (GAD), panic disorder, social anxiety, phobias, and even post-traumatic stress disorder (PTSD). These conditions may cause excessive worry, panic attacks, phobic avoidance, or constant nervousness that interfere with daily life. In treating anxiety, Dr. Kigatiira often uses a combination of therapy and, if needed, medication. Through psychotherapy — particularly Cognitive Behavioral Therapy — he helps patients understand and manage anxious thoughts, gradually reducing their fears and teaching relaxation techniques for calming the mind. When appropriate, he may prescribe anti-anxiety medications or antidepressants to help balance brain chemistry and ease severe symptoms. He also encourages holistic methods like mindfulness, deep-breathing exercises, and lifestyle changes (regular exercise, healthy sleep habits) to complement treatment. Under Dr. Kigatiira’s care, patients with anxiety learn coping skills to control their symptoms and regain confidence. Many experience significant relief as they become able to engage in work, school, and social activities that anxiety once made difficult.Behavioral and Affective Disorders
The term behavioral and affective disorders covers a range of conditions that affect mood (affective) and behavior. This includes mood disorders like depression and bipolar disorder, as well as behavioral issues like chronic anger, impulsivity, or conditions such as ADHD (Attention-Deficit/Hyperactivity Disorder) in children. Dr. Kigatiira is skilled at assessing these complex cases, distinguishing between different disorders that may have overlapping symptoms. Treatment for behavioral and affective disorders is highly individualized. It often involves a blend of therapy to modify unhelpful behaviors and improve emotional regulation, guidance for families (especially when children or adolescents are involved, to ensure consistent support at home), and medication when necessary to stabilize mood or improve attention and impulse control. Throughout care, Dr. Kigatiira emphasizes understanding and patience — he educates patients and their families about the nature of these disorders and works with them to develop effective strategies for management. With proper treatment and support, individuals with mood or behavioral disorders can lead stable, fulfilling lives, and Dr. Kigatiira is committed to guiding his patients toward that goal.Bipolar Disorder Management
Bipolar disorder is a condition marked by extreme mood swings — episodes of depression and episodes of mania or elevated mood. Managing bipolar disorder requires a careful, long-term approach. Dr. Kigatiira begins with a thorough evaluation to accurately diagnose the type of bipolar disorder and understand each patient’s pattern of mood changes. Treatment typically involves mood-stabilizing medications (such as lithium or other mood stabilizers) to control and prevent mood swings. Dr. Kigatiira finds the right medication regimen for each individual and monitors their progress closely. In addition to medication, he provides counseling and education on lifestyle adjustments that help maintain stability: for example, keeping regular sleep schedules, managing stress, and recognizing early warning signs of mood shifts. Family members are encouraged to be part of the process by learning about the disorder and how to support their loved one. Through consistent follow-up and support, patients with bipolar disorder under Dr. Kigatiira’s care often achieve better mood stability and can lead productive lives with fewer disruptive episodes.Depression Treatment
Depression is one of the most common mental health conditions, and Dr. Kimathi Kigatiira provides effective treatments to help patients overcome it. Major depressive disorder can cause persistent sadness, loss of interest, fatigue, and other emotional and physical symptoms that make everyday activities difficult. Dr. Kigatiira approaches depression with a combination of compassion and evidence-based care. He conducts a comprehensive assessment to understand the severity of the depression and any contributing factors. Treatment may involve psychotherapy, such as Cognitive Behavioral Therapy, to help patients challenge negative thought patterns and find healthier ways to cope with stress and negative feelings. In many cases, he also prescribes antidepressant medications that can correct underlying chemical imbalances in the brain, closely monitoring their effectiveness and any side effects. Beyond therapy and medication, Dr. Kigatiira advises patients on lifestyle changes that support recovery from depression — for instance, regular exercise, meaningful social activities, and proper sleep. By creating a supportive and hopeful environment, he helps individuals gradually regain their motivation, improve their mood, and return to enjoying life. Patients under his care often find that with the right treatment plan, depression becomes a manageable condition, and they no longer have to struggle alone.Medication Management (Drug Therapy)
As a medical doctor specialized in mental health, Dr. Kigatiira is an expert in medication management for psychiatric conditions. When medications (often called drug therapy) are needed as part of a treatment plan, he ensures they are used safely and effectively. Dr. Kigatiira carefully evaluates each patient’s condition and medical history before prescribing, choosing the most appropriate medication. He tailors the dosage to the patient. Once a patient begins medication, Dr. Kigatiira schedules regular follow-ups to monitor progress and manage any side effects, adjusting the plan if needed. He also often combines medication with talk therapy and lifestyle changes to ensure the best results from treatment. This attentive approach to medication management gives patients confidence that their medical treatment is optimized for their well-being and recovery.Marital and Family Counseling
Mental health issues can strain relationships, which is why Dr. Kigatiira offers marital and family counseling as part of his services. He helps couples and families work through challenges that may be linked to stress, communication problems, or the impact of a mental health condition on the family. For example, couples may seek guidance for resolving conflicts or rebuilding trust, and families may need support when a loved one is battling depression, addiction, or another illness. In these counseling sessions, Dr. Kigatiira provides a neutral and supportive environment for everyone to speak openly. He teaches effective communication and conflict-resolution skills, helping family members understand each other’s perspectives. When counseling parents and children together, he guides parents on managing behavioral issues and improving their relationship with their child. The goal of marital and family therapy is to strengthen the support system around the patient. By improving understanding and empathy among loved ones, Dr. Kigatiira not only helps to resolve present conflicts but also equips families with the tools to handle future challenges more constructively. Strong family support can significantly enhance the success of any mental health treatment, and Dr. Kigatiira is committed to helping families in Thika and Nairobi achieve healthier, happier relationships.Obsessive-Compulsive Disorder (OCD) Treatment
Obsessive-Compulsive Disorder (OCD) is a condition where unwanted thoughts (obsessions) lead to repetitive behaviors (compulsions) in an attempt to relieve anxiety. It can feel like an unwelcome cycle that’s hard to break. Dr. Kimathi Kigatiira provides specialized treatment for OCD to help patients regain control over their lives. A cornerstone of OCD treatment is cognitive-behavioral therapy, specifically a method called Exposure and Response Prevention (ERP). Under Dr. Kigatiira’s guidance, patients gradually face their fears or intrusive thoughts in a controlled way and learn to resist the urge to perform the usual compulsive action. Over time, this practice reduces the anxiety associated with their obsessions and diminishes the compulsive behaviors. In addition to therapy, medication can play a role in easing OCD symptoms. Dr. Kigatiira may prescribe selective serotonin reuptake inhibitors (SSRIs) or other appropriate medications to help reduce obsessive thoughts and urges. Many patients with OCD who follow through with the therapy and treatment plan experience significant relief — they spend less time consumed by obsessions and rituals and more time engaged in everyday activities. Dr. Kigatiira’s compassionate approach ensures that patients feel supported as they confront their OCD and make meaningful progress toward recovery.Pediatric Psychiatry (Child & Adolescent Mental Health)
Children and teenagers have their own unique mental health needs, and Dr. Kimathi Kigatiira offers pediatric psychiatry services to address those issues. He is experienced in diagnosing and treating conditions in young people, including developmental disorders (like ADHD or autism), childhood anxiety, adolescent depression, and behavioral challenges unique to the teen years (such as peer pressure or early substance use). When working with children and teens, Dr. Kigatiira uses age-appropriate communication and techniques — for instance, employing play therapy for younger kids or talk therapy adjusted for adolescents. He strongly believes in involving the family in a child’s treatment plan. Parents and guardians receive guidance on supporting their child at home and coordinating with schools when needed (such as creating individualized support plans for classroom and learning needs). The aim is to create a supportive environment around the child, both in therapy sessions and in daily life. With early intervention and proper care, many young patients overcome their challenges or learn to manage them effectively. Under Dr. Kigatiira’s gentle and attentive care, families in Thika and Nairobi find reassurance that their children’s mental health is in good hands.Psychotherapy Sessions
In addition to medical treatments, Dr. Kigatiira provides dedicated psychotherapy sessions for patients who can benefit from talk therapy. This means that beyond prescribing medications, he spends time talking with patients to help them work through emotional difficulties, understand themselves better, and develop healthier coping mechanisms. Depending on a patient’s needs, Dr. Kigatiira may use techniques from Cognitive Behavioral Therapy (to change negative thought patterns and behaviors) or offer supportive counseling (allowing patients to express their feelings and receive guidance in a safe, confidential setting). He may also incorporate stress-management techniques and problem-solving strategies during these sessions. Psychotherapy can be very effective for issues like grief, stress, relationship problems, or as an additional support alongside medication for conditions like depression and anxiety. Dr. Kigatiira’s approach in therapy is compassionate and nonjudgmental, making it easier for patients to open up. Over a series of sessions, many individuals experience significant personal growth, improved emotional resilience, and a clearer path forward. By offering psychotherapy as part of his practice, Dr. Kigatiira ensures that patients have the opportunity to heal not just through medical means but also through meaningful conversation and personal insight.Comprehensive Mental Illness Treatment
Dr. Kimathi Kigatiira is equipped to diagnose and treat the full spectrum of mental illnesses, including complex and severe cases that require ongoing management. This includes conditions such as schizophrenia and other psychotic disorders, complicated mood disorders, certain personality disorders, and trauma-related conditions. If a patient is dealing with symptoms like hallucinations, delusions, or a loss of touch with reality, Dr. Kigatiira provides a careful evaluation and may administer antipsychotic medication to stabilize their condition. He coordinates with hospitals if inpatient care is needed for acute episodes. For chronic conditions, he emphasizes regular follow-ups and consistent medication adherence to prevent relapses. He also guides patients toward useful psychosocial support — for example, connecting them with support groups or other resources. Families are often included in the treatment process for serious mental illnesses, so they can understand the condition and learn how to assist in care and handle potential crises. Ultimately, Dr. Kigatiira’s comprehensive approach means that individuals and families facing any mental health diagnosis can find stability, guidance, and hope under his expert care.Why Choose Dr. Kimathi Kigatiira?
