Depression: Symptoms, Treatment and When to See a Psychiatrist
ByEl Massar Center medical team
Published:
Depression is a medical illness, not weakness or a lack of faith. It is diagnosed when low mood or loss of interest lasts at least two weeks alongside changes in sleep, energy and concentration. It responds well to psychotherapy, medication or both, and the earlier treatment starts, the better the odds of a full recovery.
Everyone has heavy days of sadness or exhaustion that eventually pass. When that feeling lasts for weeks and starts to take away sleep, appetite, the ability to work and any enjoyment of life, it is usually depression, and it needs a medical assessment. This guide explains the symptoms doctors look for, why depression is different from sadness, which treatments work, and when seeing a psychiatrist is the right next step.
What depression is, and how it differs from sadness
Sadness is a normal response to loss or pressure, and it eases with time and support. Depression is a mood disorder that persists, affects the body, thinking and behaviour together, and can appear without an obvious cause. Under the standard diagnostic criteria (DSM-5), a major depressive episode is diagnosed when low mood or loss of interest and pleasure is present most of the day, nearly every day, for at least two weeks, together with several of the other symptoms listed below.
The essential difference is that a sad person can still feel moments of relief or joy, while a person with depression loses the ability to enjoy what they used to love, often feels guilty or worthless, and does not improve simply because circumstances change.
Core and associated symptoms
Core symptoms
Persistent low mood: sadness, emptiness or hopelessness most of the time.
Loss of interest and pleasure: nothing feels enjoyable any more, not relationships, hobbies or food.
Associated symptoms
Sleep disturbance: insomnia, oversleeping, or waking early and being unable to get back to sleep.
A clear change in appetite and weight, up or down.
Fatigue and loss of energy even after small efforts.
Slowed movement and speech, or the opposite, restlessness and an inability to sit still.
Trouble concentrating, making decisions and remembering things.
Feelings of guilt, worthlessness or unjustified self-blame.
Recurrent thoughts of death or self-harm.
Physical symptoms that are common in our region
In Egypt and the wider Arab world, many patients see an internist or an orthopaedic doctor long before a psychiatrist, because their depression speaks the language of the body: chronic headache, back and joint pain, stomach and bowel complaints, palpitations, or a tiredness that no blood test explains. When investigations are normal and the pain persists alongside changes in mood and sleep, a mental-health assessment becomes a necessary step, not a luxury.
Types of depression
Major depressive episode: the classic picture described above, which can recur as separate episodes.
Persistent depressive disorder (dysthymia): milder symptoms that last two years or more, so the person mistakes them for personality.
Postpartum depression: affects mothers in the first weeks and months after birth, and differs from the brief “baby blues” in its severity and duration.
Seasonal depression: tied to particular seasons and reduced daylight; less common in our climate, but real.
Depression within bipolar disorder: alternates with periods of elevated mood or excessive energy and needs entirely different treatment; see the difference in our bipolar disorder guide.
Why depression happens
There is no single cause. Genetic vulnerability, brain chemistry and neurotransmitters, hormonal changes and chronic illness interact with psychological and social factors such as loss, trauma, financial pressure and isolation. That is why telling someone to “be stronger” or “keep busy” does not help; such advice cannot correct an intertwined biological and psychological imbalance.
Alcohol and drug use also raise the risk. Many people who use substances start by trying to numb an untreated sadness or anxiety, and the substance then deepens the depression. This overlap is known as dual diagnosis and requires treating both conditions together.
Cognitive behavioural therapy (CBT) is the most studied approach. It helps you recognise and change the negative thinking patterns that feed depression and gradually rebuild activity. Interpersonal therapy, which focuses on relationships, and behavioural activation are also effective. At El Massar Center these sessions are part of our individual and group therapy Service, and for mild to moderate depression psychotherapy alone may be enough.
Antidepressant medication
For moderate and severe depression a psychiatrist prescribes antidepressants, most commonly selective serotonin reuptake inhibitors. It is important to know that they do not work immediately: improvement usually takes two to six weeks, and mild side effects in the first days typically fade. Modern antidepressants are not addictive, but they should be stopped gradually and under medical supervision, and treatment usually continues for several months after you feel better to prevent relapse.
Integrated care
For moderate and severe depression, the best results come from combining therapy and medication with regular sleep, daily movement (even a walk), less isolation, and avoiding alcohol and unprescribed sedatives. In rare severe or treatment-resistant cases, other options are used under specialist supervision in hospital.
When to see a psychiatrist, and when a psychologist
A psychologist (clinical psychologist or psychotherapist) provides therapy sessions and does not prescribe medication; this suits mild to moderate depression and life stress. A psychiatrist is a medical doctor who diagnoses, prescribes and follows up the more severe cases. Go straight to a psychiatrist if symptoms are severe, if you cannot function at work or in your studies, if you have lost a lot of weight or sleep, if you have thoughts of death, or if there is substance use alongside. Often both work together on one plan, as we do in our outpatient clinics at El Massar Center; for more, read psychiatrist vs psychologist.
Depression and addiction: a two-way relationship
Depression makes people more likely to turn to alcohol, hashish, sedatives or tramadol in search of temporary relief, and substance use in turn deepens depression and weakens the response to treatment. That is why every assessment at El Massar Center begins with a frank, confidential question about substance use. When it is present, one plan treats both the depression and the dependence within our mental health Services, rather than treating one and neglecting the other.
How to help someone who is depressed
Listen without judging or minimising; do not tell them that others have it worse.
Help practically: go with them to the appointment, remind them about medication, take a short walk together.
Ask clearly about thoughts of self-harm; asking does not plant the idea, it opens a door to safety.
Look after yourself too. Supporting someone with depression is a long road, and family counselling sessions can help you.
Key takeaways
Depression is diagnosed when symptoms persist for at least two weeks, and it differs from sadness in severity, duration and impact on life.
It can present with physical symptoms such as pain and fatigue before the psychological ones are obvious.
Psychotherapy and medication both work, and combining them is best for moderate and severe depression.
Antidepressants take weeks to act, are not addictive, and must not be stopped abruptly.
Suicidal thoughts are an emergency that calls for immediate contact with a professional.
Substance use alongside depression means both conditions must be treated together.
With medication, improvement usually begins within two to six weeks; with psychotherapy, within several sessions. Stopping treatment as soon as you feel better is the most common cause of relapse, so medication is usually continued for six to twelve months after symptoms resolve in a first episode, and longer when episodes have recurred. Your doctor sets the duration according to the severity and history of your condition.
Are antidepressants addictive?
No. Modern antidepressants do not cause addiction or a craving to increase the dose. What can happen if they are stopped abruptly is a temporary discontinuation reaction, with dizziness, anxiety and disturbed sleep, which is avoided by tapering the dose gradually under medical supervision. The medicines that can cause dependence are benzodiazepine sedatives, and they are not a primary treatment for depression.
Can depression be treated without medication?
Yes, in mild and some moderate cases: cognitive behavioural therapy, behavioural activation, regular sleep and daily physical activity have proven effectiveness. In severe depression, or when there are suicidal thoughts or major loss of weight and sleep, medication is necessary and can be life-saving. The decision should follow a medical assessment rather than a general reluctance about medicines.
Can depression cause physical symptoms?
Yes, and very commonly. Chronic headache, back and joint pain, stomach and bowel complaints, palpitations, shortness of breath and constant fatigue can all be the physical face of depression, especially when medical investigations come back normal. Treating the depression itself relieves these symptoms, while treating the pain alone often fails.
Heroin withdrawal begins 6 to 12 hours after the last dose, peaks on days one to three, and the acute phase lasts 5 to 10 days, followed by milder psychological symptoms for weeks or months. It is rarely life-threatening in itself; the real dangers are dehydration, complications and overdose on relapse once tolerance has dropped.
Tramadol withdrawal usually starts 12 to 24 hours after the last dose, peaks on days two to four, and the physical symptoms ease within 7 to 10 days, while anxiety, insomnia and cravings can last for weeks. It is rarely life-threatening, but stopping abruptly after heavy use can trigger seizures, so medical supervision is advised.
Alcohol withdrawal starts 6 to 12 hours after the last drink with tremor, anxiety, sweating and nausea. Hallucinations can appear at 12 to 24 hours, seizures between 24 and 48 hours, and delirium tremens at 48 to 72 hours. Delirium tremens can be fatal without treatment, so alcohol withdrawal must be medically supervised.
The symptoms of shabu (ice) use appear quickly: hyperactivity and rapid speech, chronic insomnia, loss of appetite and weight, dilated pupils, skin picking and sores, tooth decay, paranoia and, in severe cases, hallucinations and acute psychosis. Spotting them early lets a family seek help in time.
