“I haven’t had a proper night’s sleep in 19 months,” Aleksa Diaz told Newsweek. “Even if I’m physically exhausted, I can’t fall asleep. I wake up more than ten times a night—fully conscious. I only get about two to four hours of broken sleep.”
The 30-year-old from Austin, Texas, has shared her experience on TikTok (@aleksaheals) earning 94,000 views. During the video, she points out that she has not “crashed” once and wonders how her body is continuing to function.
Diaz says that her insomnia began in January 2024 and is linked to a benign tumor in her pituitary gland—a small, hormone-producing gland at the base of the brain—known as a pituitary adenoma.
According to the American Brain Tumor Association (ABTA), about 13,770 pituitary tumors are diagnosed each year in the U.S., accounting for roughly 17 percent of all primary tumors in the central nervous system (CNS).
Symptoms of Pituitary Tumors
Pituitary tumors and cysts typically arise from two main causes: pressure on the gland and surrounding structures, or overproduction of hormones. The severity and type of symptoms depend on the tumor’s size and the specific hormones involved.
The ABTA notes that when the tumor presses on the pituitary gland or nearby structures, it can lead to:
- Headaches
- Visual loss
- Hair loss
- Diminished libido
- Weight fluctuations
- Skin changes
- Fatigue or low energy
Symptoms Caused by Excess Hormone Production
Approximately 70 percent of pituitary tumors are “secreting,” meaning they release excess hormones. These include:
- Growth hormone: Overproduction can cause localized excess growth (‘acromegaly’) in adults and gigantism in children.
- Prolactin: Leads to menstrual changes and abnormal milk production.
- Sex hormones: Can cause menstrual irregularities and sexual dysfunction.
- Thyroid hormones: Can trigger hyperthyroidism, with symptoms such as weight loss, heart rhythm changes, anxiety, bowel changes, fatigue, thinning skin and sleep problems.
- Adrenal hormones: Excess can lead to Cushing’s disease, characterized by a moon-shaped face, excess body hair, easy bruising, menstrual irregularities and high blood pressure.
A Long Road to Diagnosis
Diaz told Newsweek that she has experienced many of these symptoms, beginning with severe hair loss at just 18.
“I started to feel off and suddenly began losing hair,” she recalled. “I was shedding over 300 hairs a day—just brushing my hair or running my fingers through it.”
Initially, doctors diagnosed her with polycystic ovary syndrome (PCOS). “I didn’t have any other symptoms, but I just thought it must be what they said,” Diaz explained.
By the time she turned 22, the hair loss was severe and unrelenting.
“It wasn’t stopping,” she said. “I went to a dermatologist and had a brain MRI—then they found a 5mm tumor on my pituitary gland.”
Around the same time, Diaz began gaining weight that wouldn’t budge despite dieting and regular exercise.
“I developed depression and always had a puffy, inflamed face,” she said. “The hair loss was causing me a lot of self-esteem issues.”
Over the years, Diaz’s symptoms multiplied—dry skin, dry eyes, low libido, anxiety, twitching legs and hip pain after exercise. She estimates she has consulted around 40 doctors and spent 500–600 hours researching her condition.
In 2018, she was formally diagnosed with a pituitary adenoma and prescribed metformin to lower hormone levels. “They told me to wait and see,” she said. When her insomnia worsened, Diaz suspected the tumor was causing multiple hormone-related conditions, but doctors did not confirm it.
By January 2024, she noticed new symptoms: vaginal dryness, hip pain and worsening sleep. Tests revealed her estrogen was abnormally low for her age.
“I take medication for that now and progesterone too,” she said. After years of trying everything—dermatologists, supplements and expensive hair treatments—she finally saw some hair regrowth.
Still, Diaz’s diagnosis of hypopituitarism means her pituitary gland underproduces several critical hormones.
The ABTA notes that doctors often recommend monitoring small tumors, since they typically grow slowly and cause no symptoms. But Diaz, whose tumor is 5 mm, disagrees.
She said: “Doctors believe that because the tumor is under 1 cm it can’t possibly be causing enough symptoms to risk doing surgery. The main risk is developing another hormone deficiency post-op.
“However, surgeons who do this surgery say it’s routine and not super risky, so it’s confusing as a patient.
“Cases like mine of mild hypopituitarism are often ignored, leading to a slow progression of hormone deficiencies—the very thing that is a risk of surgery.”
When she was 29, Diaz started taking hormone replacement therapy (HRT)—a treatment that replaces female hormones, mainly estrogen and progesterone, which fall to low levels during menopause.
She told Newsweek: “Doctors don’t understand why I’m basically in menopause. We don’t know the risks of long-term HRT. The medications make me feel better, but it’s not safe as a long-term solution.”
Living with the Emotional Toll
Alongside her physical symptoms, Diaz has developed severe depression and feels “literally running on empty.”
“I feel like I have hope for the future only when I manage a decent night’s sleep,” she said. “I don’t want to see anyone or socialize. I haven’t gone out in six months. It’s affected my job—I was almost fired in March.
“I’ve become very forgetful, I miss meetings and tasks and I sometimes can’t remember what I did yesterday. It’s like I have severe ADHD, but it’s not.”
A Call for Change in Treatment
Now financially and emotionally exhausted, Diaz fears what will happen if she continues to be denied further testing or surgical treatment.
“I’m worried something will happen to me,” she said. “I’ve reached my limit financially. My physical and mental health are exhausted.”
Diaz believes her struggle is far from unique. “From the time you have symptoms to when you get a diagnosis it can take 10 years,” she said.
“A lot of women have expressed they don’t feel like they are being taken seriously—and that has been my experience. Being young is a disadvantage. I’m on six medications now to manage my hormones. I’ve lost weight and my hair is growing back, so doctors think I must be fine. But they don’t see what’s really going on.”
